Every month the week im due to start my period i have these spells of shaky, nausea, dizzy, and panicky moments, my bp shoots up high and then im fine?

Pms: Premenstrual syndrome can be associated with a wide variety of symptoms that include breast tenderness, nausea, vomiting, mood changes, etc. If your symptoms manifest around the time of your periods, they may be linked.

Prostaglandin: Some women produce too much prostaglandin hormone just prior to and during their cycle. If you're not sensitive to Aspirin products, or one of its cousins, these will generally help a lot. I recommend 2 Aleve (naproxen) 2 times a day starting the week before your cycle is due. This frequently prevents many of these symptoms. Healthy eating especially a diet for hypoglycemia is also helpful.
