I started swimming about three months ago. I swim two to three times a week. I recently developped a shoulder pain on my left shoulder, and it's awful after a swim. It continues for three to four days. This is not anything like what I have experienced before; it's not a muscle pain, but it's sharper and throbbing, almost like a spasm. I mostly swim in front crawl.
What am I doing wrong to cause this? How should I treat it?
Thanks,
