Pain in the legs can be caused by cramps, varicose veins or trapped nerves.
Contact your midwife or GP immediately if one calf is red, swollen and hot.
This can sometimes be a sign of a DVT, or deep vein thrombosis. DVT is a serious condition where a blood clot develops in the veins of the lower leg. This condition can be life-threatening if the clot moves and travels to the lungs.
