Hi, i am an athlete and do a lot of strenuous weight and body training. i recently discovered the pain and discomfort yesterday but went away over night and experienced it again after my workout. its painful when i specifically push down ?

Best to rest...: Might have Strained some Shoulder Muscles. Best to Rest from strenuous exercises for a few days, apply Hot/Cold compresses as needed and take some OTC analgesics. If symptoms persist see the Doctor. Sooner is better to prevent long term injury/pain.

Shoulder pain : I agree on resting . Have this evaluated by a doctor in person. Should pain can come from bones, ligaments, and cartilage
