According to your above symptoms, it may be rounded corner disease, which is a hereditary skin disease, mainly caused by the squabble of hair follicles and has a lot to do with fat metabolism. Generally, the fatter people are, the more likely it is to happen. Hair fillet disease has no effect on life, except appearance. However, skin diseases are intuitive and do not rule out the possibility of other diseases. I suggest you go to a regular hospital in time and treat the symptoms under the guidance of a doctor.
I wish you the best of health!
