Six weeks ago I had my third shoulder surgery where the surgeon removed a loose stitch and scar tissue. He said everything else looked fine and it feels a lot better and my range of motion has returned. I am so far pleased with the outcome. He did say my tendons in that shoulder were thinner than my right shoulder, but I should be fine barring any traumatic injury. My question is can thin tendons be thickened by exercise like building a muscle? I have been a weightlifter for many years and look forward to returning to the Gym. I have been doing my physical therapy exercises for the last five weeks. Thank you for your response.
