I have Lyme and Bartonella (and past Babs) but also do have POTS....which landed me in the CCU for several days. I disagree with confusing people or adding in more treatments to complicate matters. I do many medications and then when I was in the hospital they added in two more to help the POTS. I don't like taking so many meds but am so thankful they figured out what was going on. I take Midodrine and Fludrocort and it has helped me be able to stand a little now and take a few steps at a time. I could not do this before the POTS medications were given due to my blood pressure and heart rate.
The bottom line is, everyone is different. We may all need different types of treatments but we should remain open to the possibilities and consider other options besides it always being Lyme and co-infections that are causing the symptoms.
