I'm 26 weeks pregnant and woke up at 2am with a really bad pain in my lower left leg. It had the intensity of a leg cramp but the pain wasn't coming from the muscle, it seemed to be further inside the leg. It eased out after 10mins but was very weird. I had a problem with this leg during my last pregnancy - it was very swollen for the last three or four weeks of my pregnancy and I had a couple of scans as the docs thought it might be a clot but nothing showed up. Anyone experience anything similar?
