Donna,
Has your doctor checked your thyroid level? I was experiencing fatigue, hot flashes, severe night sweats. I thought it was the MAC worsening, but it turns out that my prescription for levothyroxine was too high. Apparently, one’s need can change over the years. It’s improved now that the prescription has been reduced; the night sweats aren’t gone, but they are reduced. My blood pressure is normal (whereas it had been very low). Good luck!
