I too am suffering from SPD really badly at the moment. I've been in and out of hospital the last 6 weeks with severe pain to the point where i cant walk and am now on daily panadeine forte to help me cope a bit better. I am hoping to be induced next week because i can hardly move without feeling like im splitting in half down there. I have a degenerative spinal condition as well though which is the cause of a lot of the pain but i know just how you must be feeling. Like other BB members have already mentioned the best thing is to seek advice and support from a physio or osteopath as the pain will tend to get worse towards the end of pregnancy. I have found my physio to be great as she really understands what im going through and has been so supportive and also a belly belt has been great as it takes a bit of the pressure off my pelvic area. Hope that you find some type of relief
