Had a long flight home 8 hours, 3 hour transfer and then 8 hours again and got back yesterday afternoon. Was fine from 1pm till about 9pm last night. Fell asleep on the sofa and woke at midnight to a crampy feeling lower leg, not too painful but felt like a pulled muscle and very slightly tingly foot- not enough to say I had pins and needles. It has carried on till this morning and feels the same- its strange cause I'm not in pain ,my lower left leg just feels wierd. Theres no redness or swelling but the calf muscle does feel a bit tight. Havent done any exercise apart from a bit of a walk after the flight so dont really see how it could be a pulled muscle but that's what it feels like? And it gets worse if i bend my toes. I'm a bit worried about a blood clot but at the same time not in pain just feel a bit odd- so dont want to waste doctors time.
