My son is 4 months old, and I still have horrible back pain at times. Most of the time it's a dull ache across my whole lower back, but at other times, it locks up completely and I can barely move. Is this normal, and if so, when can I expect it to go away? I did have an epidural, about 5 monutes before they decided to do a c-section, so it was really pointless. The pain is not in the same spot that they put the needle in.
