A lot of different things could cause these symptoms, with two of either being of the pre-menstrual or pregnancy variety. For PMS, I've found that those heating pads that you can throw in the microwave for a few minutes really works well, along with plenty of rest, fluids, healthy food, and aspirin. Tylenol never works for me, neither does Midol. Aleve worked wonders, but I've heard both good and bad effects from it.
The best thing to do is see a doctor if this is out of nowhere, and especially if you're not expecting pregnancy or your monthly cycle at this time. Good luck and feel better!
Thanks, I'll have to try that if it keeps it up. I'm not expecting AF until sometime next weekend (30th-2th). Thanks again.
