I have Moderate tendinosis of the mid and posterior supraspinatus tendon, with bursal surface fraying. Grade 1 strain of the posterior supraspinatus muscle. Mild subacromial bursitis.I did 3 months of physio which didn't help and I'm currently in my 6th week of doing laser treatment and ultrasound therapy and still no improvement. Would surgery help? I'm just concerned it's not healing, I injured it in December and haven't been able to work as a carer which is a very physical job.
