Thank you for your query.
If it was a "in grown hair" there would have been some swelling. If there are no discolouration or anything else then you need not worry about it. However the itchy feeling seems to be disturbing to you and in this case I would suggest that you consult a dermatologist
for your satisfaction.
I hope I have answered your query to your satisfaction.
Wishing you al the best.
