I had surgery for a separated shoulder 4 weeks ago and the incision is still leaking. is it normal?

Leaking Wound: The incision should have sealed itself shut in this timeframe. It sounds as if you may have developed a fistula which is sometimes associated with drain placement. If you had no drains then this could be a stitch abscess which is more superficial. In either situation you should have your physician inspect the area to determine what the problem is so you minimize your risk of deeper infection.

Means: No is not normal , call your surgeon for post surgical follow up visit , will examine and treat you.
