What Causes Chronic Cough Along With Night Sweats And Migraine?

I am a 45 year old female. I have had a chronic cough since August, I am having more frequent night sweats, they believe i have A.S. in both of my SI joints, and a migraine sufferer. Generally not feeling well over all and fatigued often. I take Protonix, Lexapro, Lasix, Celebrex, and now a allergy med and flonase. They think my cough could be acid reflux or post nasal drip.... my guess could be some of both. I don't ever sleep well or more than 2 hours at a time. Schedule for sleep study in February. Your thoughts or suggestions would be appreciated. I have been checked previously for menopause as well as thyroid function. Nothing significant in results. I often feel like I have a temp.

HELP!
