Another newbie question here. In my defense, I did search for this first to avoid bothering you but there were many hits with infection and I couldn't find what I was looking for I am concerned that I am have had multiple, recurring infections in the last few years. I had two lengthy bouts of MRSA in 09, which is when it all started, and then always seem to be fighting a cold or infection of some sort (sinus, throat, respiratory, etc.). Was in ER Memorial weekend for kidney infection, strep infection on my tonsils almost a month to the day after the kidney thing. Antibiotics make me sick and I have strong negative reactions to most of them, so I'd like to head this off. I have two questions I guess: is this normal with POTS, and if so, why? I can't seem to find a clear answer to why these issues with my brain/heart/etc. would open me up to infections. Secondly, is there anything anyone does to prevent it? I guess it would require an answer to the first question. I was taking 1000mg of Vit C a day until my doctor said it is too hard on my kidneys. One doc suggested Alpha Lipoic Acid as it helps the C work better, but I don't really understand why. For the record, though my white count is always high with these infections (19+), it is normal at other times (9) and I don't have any other disorders that could seem to be causing this (though they suspect MCAS, but I don't know if there's a connection).
