I'm 20 weeks pregnant and for around 2 weeks I've had an odd pain in my big toe. I don't know if I should bother the doctor as it seems so insignificant. Basically I get an extremely sharp pain (a bit like i have a metal splinter inside my toe) if I put pressure on it from the top. I do not get it from walking, there is no swelling, redness etc. it is very hard to induce the pain it normally happens when I'm getting into bed or putting my feet up on the sofa. I can't work out what it is. I wear very sensible shoes. Any ideas?
