You might have Fibromyalgia. That's how mine started out. I started noticing it after I had my 2nd child. It was a hard birth. They say it is in your system, and comes out when there is a traumatic event, or could be brought out from just having the flu. There are all kinds of different symptoms that go along with Fibromyalgia. They can include anything from irritable bowel syndrome to migraine headaches to sinus problems. You also will have anywhere from 8 to 18 tender points on your body that hurt intensly when they are pressed on. Look up Fibromyalgia on the Internet, or read a book to see if that may be what you have. There are no tests for it, and no treatments. They diagnosed me with Arthritis at first, and ended up telling me I had Fibromyalgia. Good luck!
