Abraded skin on the glans can usually heal on its own, but it depends on the symptoms. It is recommended to eat a reasonable diet, have balanced nutrition, and do good local hygiene.
If the underwear is too tight, resulting in slight local wear and tear, redness and swelling, generally no special treatment is needed. It can be relieved by wearing loose underwear through local hygiene. If the symptoms of wear and tear are serious, and there is redness, swelling and local pain, you can apply erythromycin ointment and clotrimazole cream under the guidance of a doctor to improve it.
In addition, during the recovery period, you should also pay attention to a light diet, drink more water, and eat more fruits and vegetables containing more vitamins. Also do good personal hygiene.
