Sorry if this goes on a bit!
So, when I was pregnant with DC1 I had a period of back pain which started off as a twinge but got worse to the point of me walking home from work trying not to cry. It was just above my bottom, slightly to one side, where the knobbly bits are and I could also feel it in my buttock and sometimes at the top of my leg. It was also quite weak there ? I couldn't physically turn myself over in bed. I was about 6-7 months pregnant so noticeable bump but not a huge unwieldy one!
I came to the conclusion that the baby was somehow resting on my sciatic nerve but never saw anyone about it. The day I walked home in agony I forced myself to go to my pregnancy yoga class and it turns out the teacher had trained in magic reiki. I don't know what she did (from what I remember I think she just touched me in certain places) but two hours later it was noticeably better and two days later it had completely gone. So either it worked or the baby shifted.
Fast forward to second pregnancy same thing happened but nowhere near as bad and went quite quickly.
So now DC2 is 16 months old and I've got the same thing in my back. I'm definitely not pregnant but was wondering if it could actually have been my pelvis shifting around and now it's moving back, does that sound feasible/likely?
