Hi. Last week I woke up with a big blister on the back of my right leg above the knee. I popped it and drained it as best I could. But I could feel it seeping g the rest of that day and the next day. Now, it is a really hard thick scab. There isnt anything i could think of that ive encountered that would of caused the blister. What could cause this?

Hello,

It may be due to furuncle. For pain, you can take tablet acetaminophen. Avoid sweating. Maintain proper hygiene. In case of discharge, you may require regular dressing and apply neosporin powder.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Shyam B. Kale, General & Family Physician
