numbness and pain

I have been told by a Dr. that I have phereal nuropathy. my feet are numb, but they hurt horribly. I have shooting pain ,very sharp at times up my legs and in my feet. I have not been diagnosed with diabetes.
There are times it feels like my leg is wet, like water on it, but when I feel of it to wipe it off, there is nothing there. Is there any thing that can be done for this? Also,my hips hurt me severly,if I stand for long peroids of time and to make a bed is torture. I can’t sweep or mop a floor any more as well. I feel like one huge complaint, but it hurts so bad at times I can’t help but say something. I have been diagnosed with rhumatoid arthritis. I had rhumatic fever twice as a child, at age7, then again at13. can you give me some advice as to what to do to help myself?
Thank You
