Talk to Orthopedic Surgeon on Osteochondral Defect At Humeral Head

I went through shoulder arthroscopy 4 months ago, arthroscopy shows subacromial bursa inflamed and osteochondral defect at humeral head. Subacromial bursa was removed and I don't know what was done with the osteochondral defect. Now I am having pain but my surgeon is saying that it is muscular pain and will be okay after building muscles. He is also saying that I can lift weights and have no issue with lifting weights. Also my shoulder range of motion is improved after surgery. My question is will I be pain free after getting a good diet or not?
