i have a blob on my lip from a cut slit biopsy..the blob is next to the cut (nothing to do with it exactly)..it was big and numb at first,,then it started to go down...its still noticable though and is still kinda numb ish... i know its the local anesthesia ..i know its still in there maybe i need to do some exercise to burn it off(adrenaline and all). please tell me your experiences with a slit cut biopsy. :(
