Polymyalgia rheumatica or fibromyalgia.?
Well, since fibromyalgia is treated with Lyrica, and lyrica is a psych drug...
Go for the electric gummy bear.
Lyria treats nerve pain symptoms, which fibromyalgia is. According to my doctor (who wanted me to be on it) that is also a pain management specialist / neurologist, no one really understands why/how Lyrica works, only that it blocks specific types of pain affecting the pain receptors in the brain.
I tried Lyrica for two weeks some years ago now after my fourth lower back surgery. It gave me nightmares, disrupted my sleep and more. I stopped taking it and went through some withdrawls from it and vowed NEVER to take it again.
Taking CBD oil doesn't have any of those side effects, in fact I have had ZERO side effects from CBD oil. It's natural, legal, sold on Amazon and does not contain any THC which is the chemical that gets one "high."
Personally I've found CBD oil to be very helpful with my nerve pain and neuropathy in my feet after all my back surgeries and nerve damage. I also suffer from Ankylosing Spondylitis which is an inflammatory disease that affects the spine and have found it VERY helpful for that also. I've been able to cut my other anti-inflammatory medications by half due to the results I've experienced with CBD oil.
As with anything, YMMV and CBD oil isn't a miracle cure-all for everyone however it's worth a try as it won't hurt or have any lasting effects.
