I am having a bad case of the cold sweats today. My body can not decide if it is cold or hot. Stupid autonomic nervous system. Besides the relentless fatigue and dizziness (POTS), I think this is my worst symptom. Even worse than the pain because it is so uncomfortable and annoying. I usually get a chair and sit in the shower and let the water run over me for a while and that helps. However, something is wrong with the water pipes in my complex. Hopefully, they will get it fixed soon. What is your other worst symptom? Having difficulty with lights being too bright at times I think is a close third because people think I am a crazy lady who wears sunglasses at night.
