Had shoulder surgery for arthroscopic biceps tenotomy, subacromial decompression, and open biceps tenodesis and distal clavicle excision 4 weeks ago. now have severe catching pain with certain movements. should i be worried?

Your operating orthopedic surgeon is best to answer your question as he/she knows what your preop shoulder condition was, what exactly was done during surgery and what shape your shoulder was in at your.postop visit and what kind of physical therapy that was carried out after surgery and your response to the therapy which is in the therapist's reports.
