Help with PMDD Symptoms

Every month from the time I supposedly ovulate til the END of my period I get waves of symptoms, worse at night, and Dr's can't figure it out. My neck swells, my muscles feel too short and tight suddenly, I get intense fear and dilated pupils, dizzy and confused, sometimes I get whole body tremors during the bad episodes. Sometimes I get hives too, usually on one arm. It's terrifying and intense. I've gained alot of weight, despite eating less. Even when it's not the luteal phase, intense stress can bring on flares. Fatigue, waking up with hot flashes and tremors, cold sensitivity, migraines, low fever (around 100.8), brain fog. My crp and wbc elevate during flares too. I do not have answers but you aren't alone, for what that helps. I've been through so many drs and tests over the last 2 years. My primary dr has started to refer to me as their local medical mystery.
