Hi! I used to swim twice a week for about 30-40 laps breast stroke. One day suddenly, I felt like a muscular spasm on my left shoulder. The incident happened around 45 days back. I got my x-ray and showed to ortho although no fracture or injury got revealed. I even took a shot from a local doc for subsiding of spasm, incase it is. I am still having the pain. I would in particular mention it on my left deltoid when I lift it. Kindly help and suggest our recommendations. Regards
