On my right arm, right above the crease on the inner side is some swelling, my elbow was very painful for a while straighting it out but that got a little better. The outer side of my arm close to elbow and down to hand hurts if I try to lift something heavy or grasp something heavy. This started about 4 to 5 weeks ago and the swelling will go down a little until I use that arm a lot. I work in a office and I sit for 3 to 4 hrs a day with that elbow ( close to right where the swelling is) propped on the arm of the chair and I have my arm crooked using a mouse for that long 6 days a week. My elbow pointy bone kinda rubs on the arm of the chair depending on how I am propped or sitting. Any suggestions on this. Other than that I feel fine, can straighten my arm and lift it above my head with no problem. The mornings its kinda stiff and still swelled but I also sleep on it sometimes., no fever, weight loss/gain and no bad sweats.
