ok guys, cycling about 10 years now had probably about 5-6 cases of infection and or cellulitis over the years where I have gone to urgent care and gotten antibiotics etc. did a shot a week ago delt, it got painful over the next 24-48 hours then hardened up knotted then got red and traveled down the tricep. by then it was time for a glute shot so did that the same thing happened. the glute one got so ridiculously swollen and red it doesn't even look real. its hardened up in an area lower from the site, but its definitely decreasing and the pain has gone down considerably. I started keflax about day 3. the tricep redness went away almost immediately. I did everything from heat on the glute and delt to ice, and also taking prednisone now too which I figured would help. I don't think its an infection. but I gotta be honestly im at a complete loss for words, the delt past 2 days almost had no pain left just a small lump that was dissipating, I massaged it a bit today then it got larger, like a fuking golf ball I was able to break it apart and actually hear and feel it break up! then within an hour it hardened back up again into a golf ball with extreme pain. What in the actual fuk is going on here? the glute isn't red at all anymore and the delt is not red one bit just extreme pain with golf ball, the glute has some pain but not much left its just pretty puffy swollen. what should I do here? thanks guys
