First, more studies researching CBD side effects after real chronic administration need to be conducted. Many so-called chronic administration studies, cited here were only a couple of weeks long. Second, many trials were conducted with a small number of individuals only.
To perform a throrough general safety evaluation, more individuals have to be recruited into future clinical trials. Third, several aspects of a toxicological evaluation of a compound such as genotoxicity studies and research evaluating CBD effect on hormones are still scarce.
Especially, chronic studies on CBD effect on, for example, genotoxicity and the immune system are still missing. Last, studies that evaluate whether CBD-drug interactions occur in clinical trials have to be performed. In conclusion, CBD safety profile is already established in a plethora of ways. However, some knowledge gaps detailed above should be closed by additional clinical trials to have a completely well-tested pharmaceutical compound.

I know each case and pain levels are different. Just would like to see some positive remarks from people who suffer with it.
I am not looking for a cure just need an update on someone who took and it helped. I already know there is no cure.
I need help with the pain. I had a client using CBD from whole hemp for neuropathy with great success! The most important thing is taking it apart from other medications esp for heart, and giving yourself enough of a dose. If I were you, I would just go slow for the first few days then go up.

I'm scared of flaring everything. Nerve damage across buttocks from a surgeon who found the nerve stuck to the bulge during a laminectomy operation and prised it off. I haven't sat for 5 years and getting worse. A muscle in my buttock is now throbbing constantly and causing pain to the muscle above.
I've only started taking it today but the muscle pain is still as painful. Does it take a while for it to work. Only started on low dose to see what happens. Karen August 13, I have idiopathic peripheral neuropathy I picked up some CBD oil yesterday morning. I am prescribed to take 75 mg of lyrica 3x per day.

I've nerve damage across buttocks from a laminectomy.
I've not been able to sit for 5 years. I've recently started with a muscle spasm in my left buttock and the muscle above is painful. It is only the first day, also tried a cbd night time tea as well. Do change in muscle pain so tight on my left hand side. How long before felt it starting to work please.
I'm trying not to expect changes straightaway. I also take mg gabapentin and 30mg amitriptyline and I hate both of them - they both can cause muscle tightness affecting the nerve.

My dad has severe advanced stage Dementia. Will CBD oil help him at this point? He is now refusing to eat any solid food, but will accept most drinks. In addition, he has lost a great deal of weight even though they're giving him Mega Shakes containing a full meals worth of proteins, etc. The results build up over time. We should have you have a one-one chat with our Wellness Consultants. In the beginning, I was a sceptic, but it worked so well that I ordered three more bottles to last me for a few months.
I started to take CBD after I had a hard time sleeping due to bursitis in the shoulder. My trips to physical therapy only aggravated the pain issues from inflammation.
My doctor and PT prescribed ibuprofen but when I used their prescribed dosage, it caused me more gastric problems than normal. Since using CBD sublingual at 5 drops of mg at night, it seemed to help me get through the night and I stopped completely the use of over the counter pain relievers.
An added unexpected benefit of daily nightly CBD use, was that my Gerd symptoms that I had for years disappeared and allowed me to stop taking Prilosec daily. For pain during the day, I use CBD as needed. I think CBD is a great natural alternative to pills. All in all, I am very pleased with CBD and expect to continue to use it moving forward. I am 68 years old and I believe that CBD for me at my age is a great thing!.
I would urge you to stop taking CBD immediately. I smoked before bed and feel asleep but when I woke up it felt like I was dizzy going to pass out with no oxygen to my brain and I had a tingling sensation in my head is that normal??
Can CBd increase ur anxiety? That would be a very unusual response. CBD can make you feel dizzy, but this is usually very brief and promptly after taking it. With the recent boom in popularity, there are quite a few poor quality products circulating out there. Apperently cbd oil makes my foot fall asleep. Any explanation to why this is happening? That is definitely a very unusual response to CBD. My mom is taking a CBD oil and recently changed brands.
If you or your mother would like to call one of our stores a Wellness Consultant would be happy to talk you about other options. If you purchased your product from us you can return it for an in-store credit or we can help you find a different CBD product.

My family is full of addicts and I was always afraid to be one of them. My list of problems are as follows: He recommended that if I go the CDB route, I use it topically as to not upset my already angry-all-the-time digestive system.
I have no way to quickly get to a hospital if I start to freak out or anything. I need a solution, I want my life back. I need to know how to be prepared if I want to try this as my last resort. I am so sorry that you have so much on your plate. Even just one of those health conditions would be a lot to deal with. Some people respond better to an isolate vs full-spectrum, etc. So will see if all of this is caused from the oil!!!!
Hi Darlene — Wow! There are a few things that could trigger reactions like that. First, low-quality CBD products can be diluted or contaminated with other ingredients. With the recent boom and availability, many shady businesses have begun producing poor quality CBD extracts.
Third, you may be taking too high of a dose and need to radically back down. Some people are more sensitive to drugs, supplements, foods, etc. Give us a call or drop by one of our store locations and we can help you find something else that actually works for you.
What is considered a high dose? Thank you, Denise Evans. The answer is two-fold. For those who are more sensitive to CBD, a daily dose may be half the recommended dose for them to see amazing results. If you ever run into any questions, feel free to call us. I started getting headaches as well but as my body got use to the oil the headaches left.
Also some companies use grapeseed oil and that gives me a headache as well. I am a type 2 diabetic with hypothyroidism and sleep apnea, will this help with these health issues and possibly lose a few pounds in the process? Hi Lona — Yes, CBD can be helpful for diabetes and there have been reports that it has proved helpful for sleep apnea as well. Give us a call and we can get that scheduled! It can certainly cause your head to feel strange in high doses.
It was scary but know that nothing bad can happen. The effects unfortunately at high doses can last for hours. It was almost 6 hours of strange discomfort. I thought I would end up in the hospital. I also noticed I had very good dreams while on it.
I wanted this to work, I really did.
