I have Rheumatoid Arthritis. The nodules growing on my knuckles, foot joints and lower back are very painful and eventually, without care, they could 'fuse' the joints which leaves the body part mis-shappen and immobile. I have many issues with holding on to vibrators, repetitive joint movements, positions and pain. I take many hot baths to loosen up the joint area, take 3-4 aspirin and take frequent small breaks to move around and then get repositioned. It all depends on how I feel which varies daily--but the more advanced the disease, the more I need to work with it.
