How many of you have had high C4a levels? It is supposed to be 2830 and mine is 7436 I think or there about. Alternative med doctor said that could be lyme or mold, but have also read that those of us with CFS can have high levels. My lyme test is completely negative. My sed rate is normal and so is my CRP; although, they have been elevated at times. I have had so many tests go positive and negative, I'm totally overwhelmed. Freaking out because I got even more sick after vaccines the end of November and afraid that there is a bad mold problem in here because of off and on nasal stuffiness in sinuses and ears, etc. I'm quite the worrywort, but this is scary. I'm so sick of all this because there have been so many things that come up with folks that have been said that are making them sick. This is awful and depressing. The last ID doc said that they can't figure out what is making people sick with this and that we should be careful whenever people say they have a cure. This alternative doc wants to give me cholestyramine (Questran), which I probably would not tolerate. I'm so depressed I could just scream.
