I constantly have pain in my hands and joints. It feels as if I sleep on my arms during the night and they re spending all day waking up. When I open and close my hands, all my joints crack. My grip is weak and I have to constantly adjust my hands, wrists, shoulders, arms, and neck in order to loosen them up. I feel tired most of the time and find the sensations in my hands to be very distracting. I m only 18, but I think I might have juvenile arthritis. I like to get a second opinion, so what do you think?
