Pregnant and waking up with charlie horse cramps that lock my foot in a painful pointed position.what causes this and how can i stop it?

Dehydration: Most commonly pesky charlie horses occur during sleeping hours and frequently wake people from sleep. Drink plenty of water and keep a glass at the bedside for just such an occasion. Some people also swear by supplementing their calcium and magnesium which are very important in the chemical precess involved with muscle spasms.

Pregnant foot : Congrats on pregnancy. Although you may not recall any injury, your foot may be having problems with the extra weight associated with pregnancy. Your arches ( the ligaments, tendons, joints, that hold it up) may be needing support, rest, and ice. Hope this helps, best of luck and congrats again!

Pregnancy: Many things are changing during pregnancy. Blood, heart rate, electrolytes, skin, hair, breathing, GI , urinary changes; too many to count. Talk to your ob/ gyn if you have concerns, but most of the time this is part of pregnancy. You can also look online for concerning symptoms.

Quinine: Buy small bottles if tonic water with quinine at the supermarket. Drink 1 bottle before bedtime each night. Ask your OB about prenatal vitamins. Eat a banana each morning.

Magnesium: Try magnesium supplementation or soaking in an epsom salt (magnesium salt) bath. Be sure to inform your ob/midwife about this as magnesium can stop and/or weaken contractions when the time comes. :).
