SPD sufferers can you describe your symptoms and the pain to me as best you can? I'm 21 weeks and have had bad RLP most of my pregnancy however lately it's been so bad it makes me nauseated. Usually it's on my left side. it's so intense that I can't lift my leg or bed down at all. It's hard to describe the pain, mostly muscle feeling, not bone. it's not all the time, but has a burning characteristic to it as well as a lot of pressure. so much so I feel everything is going to fall out of me sometimes. it's worse at night, laying down does alleviate it, but as soon as I move it's horrendous again.
