Thanks for calling H.C.M.Forum.
You have multiple connective disease like rheumatoid arthritis
, sjogrens, hashimotos and using many power ful drugs like fentarnyl 100, etc.
All the drugs you are using are for pain relief we will search some thing for prevention.
I advise you to follow some diet recommendations as Take more water, fruits and juices.
Avoid taking potato, other tubers, tomato, cauliflower, egg, chicken, fish, and all sea foods, By this you can avoid more pain.
Avoid taking oilyfoods, junkfoods, and spices, which will improve the secretions of saliva , tears, etc.
With your doctors advise you can have neurotropic injections periodically to lessen the intensity of pain.
