I have been taking winstrol for about 3 weeks. I switch off the injections in each shoulder. This last Saturday I injected into my right shoulder with a 1.5 inch needle (pushed all the way in) and over the next two days I have been experiencing excrucruciating pain. I have a knot in the area where I injected and all around there I am experiencing swelling. I am really worried about this because it has not gotten better in 3 days. My range of motion has improved very slightly but the pain is still there and very intense. Has anybody ever experienced this before or can somebody give me an idea of what I might have done??
