If you have a confirmed subscapularis (SSC) tear, then treatment will depend on the nature, degree and inciting event that cause the tear to occur.
If it is a small tear involving only portion of the tendon, then this could improve with conservative management such as physiotherapy or with a PRP injection.
In situations where there is a more significant tear, you may require a surgical repair, but this also depends on whether the tear is acute of chronic/degenerative in nature. I would suggest getting this assessed more thoroughly before making any further decisions about your treatment.
Hope this helps.
