I have been healthy except for the past 8 months I noticed almost a hard bump on my humerus. X-RAY and Ultrasound results for my upper left arm was negative. I also have experiencing joints and bone pain and joints cracking. I have been referred to the rheumatologist and after some blood tests my RF was negative but ESR=25. For the past month I experience some wired feeling like burning, tingling and light weakness to my left and arm. I avoid lifting heavy objects. Past two week ago I noticed a bump on my left forearm under my skin. It is hard and not moving. Today I felt the mass is bigger not moving and by pressing it my arm and hand started to slightly ache and burn.

Till then, you should do following to have relief:- Take a mild analgesic like Advil.- Eat healthy. Fresh fruits and vegetables are helpful.
