Hi everyone, i too had this, a lump and very sore all down right side, went to my own GP who said it was a graze from the delivery, gave me some anti biotic cream which made no difference, went back to hospital on Monday for my 6 week check up and the doctor said it was a flap of skin which is normal, i cant remember the name of it but she basically took it off, it was a little stick with black on the top of it! It bled for a few hours was a little stingy but i am so glad she did it cos i am feeling alot better now!
i'll google and see if i can find the exact name of it/procedure!
