A jumbo egg
blister, ouch! I dont know your full medical history, but based on the information you gave me, it sounds like your
diabetes is advance. Diabetics with advance disease have poor
wound healing. I unfortunately have taken care of many diabetic patients who have developed ulcers, skin infections, and even bone infections after popping a massive blister. Again, I dont know how bad your diabetes is, but to be safe, I strongly advice against popping your blister.
The response written above is a
medical opinion, and does not substitute an evaluation by a medical professional. I cannot guarantee accuracy in my answer, especially when I cannot physically evaluate you, and do not know your past medical history, all of the medications you are on, your lifestyle habits, etc; therefore I cannot be held liable for any consequences that occur as a result of my opinion.
