Shoulder agony while swimming.
I have been swimming for vitally 4 years as well as playing water polo. When swim season started up surrounded by February i noticed a pain surrounded by my shoulders ( kinda like the high outside of the upper arm) that feel like it was from lactic bitter build up but really intense and it was after swimming just a few hundred yard at a slow pace. I tried stretching and used IBuprofen to get through the swim season and it seem to kinda go away. I played water polo since swim season concluded ( in may) which is mostly head-up swimming so i didn't seem to hold any pains. I just started swimming a few weeks ago ( head-down) and the pain is posterior. It feels like a massive build-up of lactic sharp. Maybe lack of blood or pinching nerves? Maybe my muscles are really tight and knotted from not stretching? Any minister to would be appreciated.
Answer: It sounds to me that it might, might be a rotator cuff injury, not necessarily torn but maybe the ligaments are stretched and over used.
hope its of help
