For the past three weeks I've had pins and needle with burning pain in my outer left thigh. Almost like electric shock sensations. I've read that it's likely the weight of my belly putting pressure on a nerve in my pelvis...which means it won't go away until after I I've birth. I'm only 15 weeks and the pain is becoming unbearable. Does anyone have tips on how to cope? Laying down seems to make it worse. Please help.
