Hello & thank you for posting on HCM
It seems you have developed acute sprain
of the shoulder due to continuous exercise.
You have done right thing by stopping exercise & also you must be seen by a Dr who may advise re getting a XR done / USS in order to rule out any ligament / muscle tear.
Also take some pain relief (paracetamol
) with anti inflammatories which will work better than local cream applications
Depending on the test results you may need rest+ gradual physiotherapy
OR surgical repair if there is any torn muscle/ ligament (depending on degree of damage)
Hope this helps
