It's getting so uncomfortable and annoying. I get 5-7 an hour, lasting anywhere from 2 minutes to 20 minutes! Anytime I stand up or walk it gets worse...that is when they last about 20 minutes. I'm keeping track of my water and have about 10 glasses a day along with a glass of juice and a Seltzer water. I get them even when I'm resting...last night while watching TV I had 5 in 1 hour. Sometimes they hurt and sometimes they don't. I have a Dr appt tomorrow afternoon so I'm going to talk to them about it. It's been about 2 weeks now and getting increasingly worse.
