Frozen shoulder or adhesive capsulitis is a very common cause of chronic shoulder pain causing restriction of movements. Although self limiting can be very distressful for the patients affecting activity of daily living like wearing clothes,combing hair,etc. Suprascapular nerve block reduces the pain thereby making rehabilitation much easier and faster.
Also rotator cuff tears, tendinosis can give rise to chronic shoulder pain and regenerative therapies like platelet rich plasma (PRP)can be done for partial tears helping in faster recovery.
