My mother is diabetic, and I heard that because of that their immune system is weaker, hence more skin conditions. Recently my mother is starting to get these small red bumps, at first they only itch, but then as she scratches it, these small red bumps will start to grow really big, and it becomes much more painful, and also itchy at the same time. The shape of the bump looks like a pimple, or a spider bite.
The first time when I took her to her primary care doctor, the doctor said that it was just bug bites, although I refuse to believe that because our house is really clean. However we did clean the house down one more time, but these symptoms keep recurring. The second time I had to take her to the ER because the bump is actually on her face. The doctor there diagnosed her with "MRSA infection".
Now, I looked up MRSA infection over the internet, and the symptoms are really similar, however my mother never got any cuts anywhere, and these red bumps are just coming out of random places. I also read that MRSA infections are deadly, which is why I am really concerned.
As far as we know, my mother is not allergic to anything, so I don't think that this is an allergic reaction. Could this be a symptoms of a autoimmune disease? Or could it be a sign that her diabetes is getting worse? Or is it just simple a MRSA infection? If it is just a MRSA infection what can she do to prevent these red bumps recurring?
Thank you in advance
