Thanks for posting your query.
It seems that you have hurt your XXXXXXX The small white area that you can see is likely to be due to the skin color changes due to hematoma
formation in the area. The numbness
is due to the localised swelling and will recover spontaneously.
You need to watch out for the signs of infection like pain, raised temperature and an increase in the swelling. Systemic antibiotics and local drainage
might be needed in case of infection. The color changes and the minor numbness will recover on their own. Please do not worry.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Dr. Praveen Tayal.
