The color of the fluid seems to be yellow-ish in color and tinged with blood.
I don't see any pus per se.
The blister developed about 2 days ago and has gotten progressively more painful. It is about a centimeter in diameter.
The skin is broken. It ruptured last night (around 12 hours ago).
Thank you for the information. I have already bandaged the area and applied an antibacterial cream. However, as I am not able to go to a doctor soon, can you tell me what an indication would be that I should be more concerned with the blister? Also, if it continues to worsen, in your opinion would starting an oral antibiotic like amoxicillin be prudent?
Thank you. This is very helpful.
