Thank you, Dr. XXXXXXX
The bruise is in the inside of my calf, extending around to the back of the calf. I tripped over a box and fell - that is where the bruise has appeared. It is VERY swollen and the skin around my leg is very tight. The blisters have appeared on the surface of the bruise. The blisters appear to have yellowish-red liquid in them. Not red like a blood blisters...
Thank you, again.

Thanks for writing back.

Based upon your description I suspect the bruise you had after injury has got infected and presented with a blister.

This is very common and can be easily treated by a course of antibiotics with or without incision and drainage of the blister.

The blister if left unattended will grow and may break discharging the pus.Do start a course of antibiotics after discussing the same with your treating doctor.

Wish you good health.
