Hello Pandalili,
I just read your comment above and I too have a simular problem. I had a TT and am experiencing pain in my upper right side of my belly since two weeks after my surgery. I have been through all kinds of testing.. blood, kidney, gallbladder, pancreas, stomach, CT scans, MRI's and pain management since about early june 07. Today I still have no answers and might have to go back under the knife to look inside to see what is wrong. My gastro doc told me it could be a stitch on a nerve, or that something was left inside me at the operation. But it definetly was not any of my organs and my blood work is fine. If you get any answers, please post back here as I will do the same for you.
The residual 'bumps' above each nipple could be due to any number of minor post-op problems including reaction to an underlying suture (suture granuloma) or a small area of dead fat with surround scar tissue formation (fat necrosis). In either case, if the problem does not resolve, exploration and removal would be appropriate and likely a minor procedure.
I do not know what the cause of your periumbilical discomfort following a tummy tuck. However it seem incongruous that you are frightened about a minor biopsy around the previous breast surgery, and yet are willing to undergo a blind laser procedure around an area with an unknown source of persistent pain in your abdomen. It seems to me that this should be resolved before undergoing additional elective surgery there.
