So, after my ride today, I took my BP.. 92/50. No wonder I was tired, but the other thought that my BF and I tumbled onto was that the meds I am on are a low dose combo HCTZ and diuretic. My legs have been aching lately. Duh. One of the signs of low potassium is leg pain. HCTZ makes people prone to low K+, as does the massive sweating I have been doing with my riding in the heat this past week. You'd think that 2 people actively working in the medical field would have thought of this sooner, but nooooo. So, off to the banana store, and then call to have labs drawn. Maybe I can stop the meds now though!!
