Although I have been diagnosed in November with PSA, I'm still trying to understand it..I guess I always thought of arthritis being joint pain alone . At the moment my kenalog injection is wearing off, I have this achy feeling all over my body as if I have the flu, pains in shoulders and it feels like my tendons/muscles are inflamed, some pain in thumb.. I am also so tired and my mood is low... Before injection had more pain in joints and heat from joints affected,also lump appeared in one of the joints. Is this normal for PSA ? Most of joint pain I have is on right side, also do you also get heads aches from pains in neck joints? Sorry I have so many questions..
