Why has my scar suddenly started twinging?

No

No

I appreciate all the responses. I hate going to the doctor and paying the co-pay. It is a comfort to know others have experience discomfort from old scars.

Also sorry I put this in the wrong forum.

You really should still have the doctor test it though. Maybe go straight to the dermatologist to save the intermediate co-pay. Any sudden change in a traumatized area shoudl be checked for signs of lesions or abnormal cells.

IANAD, etc.
