No feeling, no pain. Is it serious. Do you need to mind it
This situation may be caused by external force collision or friction, but I don't realize it. I can usually observe some changes on my skin. If it dissipates, there will be no big problem. If it hasn't been improved for a long time, I can go to the hospital for skin examination to see if it is caused by some other reasons. I can promote the dissipation by local hot compress
The position on the hand is not like a scar, and the local skin is blue. The cause may be the blue caused by local skin blood stasis after friction or collision. If you don't have any symptoms of pain and itching, you don't need special treatment first. You can apply hot compress on the part with a hot towel to see if it can be relieved.
In daily life, we should try to avoid trauma, skin friction and other injuries that may cause scars to the skin. If there is a relatively large trauma, it is recommended to use silicone gel or silicone dressing in time after wound healing.
