Hi Emma. I was sore after my birth for about 4 months, before I finally sought treatment. Prob diff to you though, most of my pain was in my lower back and pelvis etc. When I had contractions during labour, the pain always centred on my lower back. I tried craniosacral therapy, which is very gentle, and now I'm completely pain free. DS also had a couple of treatments, as he had very bad reflux and was in a lot of pain too, and he turned into the most contented happy baby after treatment. The first thing I'm going to do when I come home with my next baby is book us both in for a treatment, it was so good! Here is a link to some practitioners in Auckland, and some more info about it if you're interested:

Craniosacral Therapy is a hands-on energy healing technique, whereby therapists gently mobilise and release the craniosacral system, which includes the soft tissue of the head (cranium), the spine down to its tail end (the sacral area) and the pelvis. It focuses on the cerebrospinal fluid, which is produced and absorbed by the body and in particular, the irregularities in the flow of this fluid.

Craniosacral Therapy helps to boost general well-being, reduce stress, improve quality of sleep, increase energy and enhance the functioning of all the body's organs. It is a non-intrusive therapy that works with the entire structure, physiology, mind and spirit. For a treatment, clients usually lay on a massage table and the therapist works through light clothing. It is a very gentle and profoundly relaxing procedure that lasts between 40 to 60 minutes.
