Thank you for asking on HCM!
I understand your concern and would like to explain that Lyme disease
is a chronic disease, which can affect many systems of organs, including the heart, muscles, skin, central and peripheral nervous system
Based on your symptomatology, the fact that you symptoms disappeared while on antibiotic therapy and reappeared, means that this is a chronic infection.
Have you been tested for both antigens and antibodies
of Lyme disease or only just antibodies?
Sometimes the antigens can persist in the blood for years, indicating a chronic infection, even though the antibodies don't show this.
I would recommend consulting with an infectious disease specialist for further tests for Lyme disease.
An ambulatory 24-48 hour monitoring is necessary to examine your heart rhythm, for possible cardiac arrhythmia
If you were my patient, I would continue the treatment with antibiotics, as it seems that this resistant bacteria is still causing disturbances on your body organ function.
Hope to have been helpful!
