What Causes A Leg Blister And Painful Spider Bite Lumps?

I qoke up with a clear to yellowish blister about 3/4 of an inch, oblong, on thr upper part of my right leg. I do get spider bites alit, but they are more of a painful red bump...no blisters. I have also had 2 operations for serious MRSA infections. I am 58, have Addison s disease and felt kind of yucky last few days, but usually vry active and happy.

Hello,

I can understand your concern for the leg blister and painfule lumps. After analyzing your query I can make a possibility of insect bite hypersensitivity.
It is quite important to not to touch or pinch or pop the area as it can get secondarily infected. I prefer to give an antiboitic in your kind of illness according to the body weight. you can meet a doctor and take further guidance.
Till the time you meet a doctor you can apply an antibiotic cream containing mupirocin and take antihistamine such as cetrizine.
All the best.
