They only last a few seconds. The build and
peak like labor pains. Say I'm in the kitchen and
I'll feel it coming on so I have time to brace myself. I'll set down whatever it is i'm holding and get ready. I have to cross my legs, bend my knees, hold on to something, clench my body tight, and try to breathe. Thank God it only lasts a few seconds. My 14 yr. old son witnessed it yesterday and tried to call 911. I kept signaling him not to. I knew it wouldn't last long. My gyno.
