OK
Recently, whenever I get scratched and develop a wound, it takes a very long time to heal and often gets infected again. After about ten days, the wound healed, but it left a scar like in the picture that doesn't fade. The scar in the picture is a month old, but it has become a permanent scar like that.
I'm worried whether wounds that don't heal well are due to aging or my immune system. If it's not aging but just a simple health issue, should I go to the hospital?
