Hi all. I'm 20 weeks and have recently started to experience a pain deep in my left buttock when I walk or put pressure on the left side. It doesn't happen when I'm sitting laying down nor does it correspond with lower back pain. It's not a muscle pain and I haven't stretched it. It;s quite deep within - almost like nerve pressure. When I walk the pain shoots up/down and I end up buckling my walk. Means I hobble around. Is this common? Has anyone else experienced this? If so, how did you manage it and did it get better? I'm planning on calling my midwife/GP tomorrow about it as I find it quite debilitating. Many thanks in advance x
