Help. My wound keeps getting worse and worse. My doctor's office keeps saying everything is OK. What can I do? (Photo)

I am sorry to hear about the incision line healing problems you are experiencing.  These types of complications can be quite (understandably) distressing to patients;  unfortunately, sometimes the wounds do look worse before they begin to look better. The wounds tend to occur where incision lines come together (where there is the greatest tension and least blood supply).   In my experience, these types of incision line problems tend to "fluctuate" in appearance during the first two months after tummy tuck surgery; the vast majority of patients are fully healed by the two month postop mark.
 Sometimes removal of a exposed suture and/or removal of any unhealthy tissue will expedite healing.  There may be different treatment modalities recommended; best to "stick with" your plastic surgeons recommendations. Generally, this will involve application of some type of sterile dressing ( in my practice I use a non-stick dressing covered by a sterile dressing once a wounded is clean).  Also important to concentrate on a healthy diet, including good protein source.   Obviously, avoiding any form of nicotine is also important. 
 Although your plastic surgeon will be your best resource for definitive assessment, advice, and meaningful reassurance,  I think you can have  have peace of mind that these types of wound healing problems generally go on to heal over the course of the next several weeks, often without long-term sequelae.   In other words, unless something changes dramatically, you should be just fine long term.Best wishes.

thank you for your question. Woundhealing takes it time and usually gets worse before it gets better. You have to continue with the wound care you are doing now and if you feel uncertain about the progress you can visit a wound care specialist close to home. Best of luck
