Try some dermatix, i had a lumpy hard bit on the end of my scar but it felt like it was under the skin too. Iv been using it about 2/3 weeks now and i love it and its already making difference in the colour and the feel of it xx worth a try. Had a look at your pic, and it kind of looks like a scar left when iv had a bad spot of that makes sense. I could be wrong. Have you spoken to the nurse ? Xx
