Hey, just a quick thought. I also had an EKG because they were concerned about my heart, it came back fine, but they said I had developed early repolarization which is considered normal because my heart rate is so slow.
Additionally, I've been fighting with some chronic epididymytis for the past few months. I take antibiotics, it goes away, as soon as I stop the antibis it comes right back, and then I have to start on antibiotics again. I've done doxycycline for up to 30 days, and I just finished 30 days of bactrim.
Your mention of the messed up cholesterol levels just jolted my mind, and I thought maybe although those things seem completely unrelated to me, perhaps they are part of the bigger picture like the cholesterol levels.
