Normal or Not?

Kelly • I`m an elementary school teacher and wife to an amazing man with a passion for making changes in the lives of children.
Every once in a while I get cramps that Will make me throw up from the pain and feel like I'm about to feint. My limbs feel like they are on fire and tingle for about an hour. Is this normal or a cause for concern? My husband is worried. Thanks for any help or advice!
