I had a tummy tuck six months ago, am now getting blisters on my stomach, painless, what can be cause? 53 years old, great health

Probably unrelated: Unless you have lesions over suture lines , either in the midline or the lower abdominal scar, that could indicate suture related issues, blister are not explained , this far out, from tummy tuck. You may need to see a dermatologist.

Not Related?: Based on your history, it is very likely that the blisters you are experiencing are not related to the previous surgery performed. Best to be seen by your physicians for in person examination and treatment recommendations. Best wishes.

Maybe...: It might be that the area in which the blisters are forming is in the area where you are numb, so you are not feeling your clothes rubbing on the skin. If this is the case, careful padding is usually all that is required. Otherwise see your surgeon. http://www.psinteractive.net/abdom3.htm.

See your surgeon: If the suture material used by the surgeon is permanent (does not dissolve), it can on rare occasion be expelled from the body. This will usually show up as a blister with a little redness around it.
