Hi Doctor, My son took a vaccination for 1. 5 years of age one month back. he got swelling for 2 weeks. now swelling reduced but that thigh area got light black color. is this any issue?

A. Thermophob you can apply basically the swelling should also not last for two weeks is high time that usually subside within 24 to 48 hours if you do cold pond and if you apply this tube you will never face this problem but as of now you can also consult your doctor once
