I had night sweats, fatigue, headache, the occasional cold sore. stuff like that over the past 5 months. what should i do?

See a doctor: Hi. Unless you're sleeping under too many blankets or the heat's on too high, night sweats need evaluation. Your gender's not stated, but it's a little early for bad perimenopausal symptoms. Talk with your doc about this, and get the appropriate diagnostic tests. Good luck!

See your doctor: Hi. Having those symptoms for 5 months is not normal. Any weight loss and/or loss of appetite? I'd suggest you see your doc for a diagnostic evaluation.
