Intracutaneous sterile water for back pain in labour.

Intracutaneous sterile water appears to be a simple, effective, and harmless technique for relieving back pain. This technique has been used to relieve pain of renal colic, whiplash, and back pain in labour. Family doctors often practise obstetrics in small or isolated units that have limited options for pain relief in labour. This technique is simple, is easy to learn, and appears effective for relieving back pain, which complicates about one third of all labours.
