Hi Guys. I just came back from the ID doctor and am concerned because he told me he has never seen anyone with chronic Mycoplasma IGM titers for such a long time! It's been 2 1/2 years since I got infected and I still have positive IGM levels of Mycoplasma in my blood! My question is: Has anyone had long term Mycoplasma IGM levels show up in blood work? Mikie, I know you had a Mycoplasma infection...so maybe you can help with this. When an infection is CHRONIC, is it the IGM or IGG levels that show up positive in blood tests? Also, how long does the IGM stay positive or active? Not only that, the stupid doctor told me that if I'm feeling fine, no matter what the test shows, he is NOT going to give me Antibiotics! I couldn't believe that! To top it off, he says I only need 3 weeks of Antibiotics and then I'll be fine! What is wrong with these doctors??? Do they not read or do research? How can an Infectious Disease Dr. tell me this?? I'm just so confused and tired of all this. If anyone knows anything about this or has had a similar experience, please let me know. Thanks a bunch.
