I have pain in my fingertips, very tender thin nails, often painful to the touch. I have weakness in my hands. Can not grip to open a jar, or sometimes a bag of chips. Pain runs up my arms to my elbows. I have pain in my neck, shoulders and tiredness in my arms. I have been having these symptoms for some time and feel that the doctors I have seen often pass it off as my weight problem. I feel my current medical conditions are causing my weight problems. Can you offer me any advice, or help.
