Hello I would like some advice please. I had key hole surgery on my knee on November 21st of this year and Im healed but one of my scars has started to bubble up and it feels hard were as the other is completely flat. Could it just be extra tissue or could I have an infection under it. Thank yoj
HI, thanks for using Chat Doctor Fibroid or scar tissue tends to be firm or hard to the touch. This is normal response to any trauma including surgery. Normally the area is not painful. It is not usually indicative of an infection. I hope this helps
