Good observation Nikki, I had my scar revisited by Dr Rutka @ Toronto General a little over 2 years ago. I had a lump that you could see, feel and let me tell you it was extremely sensitive to touch. Before the scar neuroma was removed I too had several rounds of steroid injections.
Mei Mei, my Dr used local anesthetic in an operating theatre, so the surgery was relatively a breeze. I had a nurse who sat on a little stool watching my vitals, telling me to breathe, holding my hand and rubbing my arm. I had another nurse rubbing my leg. It is amazing how soothing human touch can be, I know it really helped me to stay calm. (I did post about my experience, I just do not know how to retrieve it.) I went home on pain killers, I think T 3's. I was sore and than tender for about 2 or 3 weeks. Today when my face is jerking around and I have a headache my scar gets red and is sensitive to touch. I use a pain relieving cream on it.
Take care,
Anne Marie
