Hey geg,
just gotto say ive got a similar problem on my RHside, when i hold my forarm parralell with the floor and pull my shoulder back i have a thick line that runs from the armpit to the nipple, this seems to be were the canula has passed through and has left scar tissue, its pulling tight across my chest causing an indentation/ridge.
looking at your pics your left pec about 4 inches up have you got a lump of scar tissue?, it looks as tho you have and thats exactly were mine is, but my LH side is fine!, and as regards to the lines that run across your chest i have one aswell, if my situation doesnt improve im going to get back in touch with levick, as asked him what my chest would look like when gyne is removed and he said "just like it is now, but without the lumps", i also said a few times to him that i didnt think i needed lipo because the fat hadnt increased on my chest at all, it was just the hard lumps that were the problem!, now me being in to weight training my bodys apearance means everything to me and if this big scar doesnt sort itself out im gunna get in touch with him.
