I am maxed out on cymbals and neurotic due to my kidney disease; but I have had terrible breakthrough pain.
My girlfriend..Who is newly diagnosed but has had chronic pain for years uses lidocaine patches for breakthrough pain. I asked my MD and he said was a really good idea..Now I have them too. It is helping a lot..Reduces the pain to make it bearable.
diclofenac Sodium Topical Gel 1%. I didn't think it worked at first, but found it good in the middle of the night if the pain wakes me up
Before being diagnosed for chronic migraines, FM & CGS, I lived on ICY HOT & ASPERCREME. It was a GODSEND. Still use it, sometimes instead of gabapentin if pains are mild. It was nothing unusual for me to have 1/2 head of hair slicked down w/a topical cream. Good luck & best wishes. ((((())))).
