First, I'd like to say, the prolapse after your hysterectomy was probably not due to lifting something too heavy, but rather the result of why you had prolapse to begin with.
In terms of your anterior repair, yes some of the tissue swelling, and scarring will improve. Continue to keep your surgeon abreast of your symptoms and progress. Also, I'd remind you that anterior repairs have a high rate of failure (~30%) even in the best surgeon's hands.
What if the bump does not receed?...Should I get a second opinion?
I am now 6 weeks post op and it is still there. what will happen after?
