It's a cross between someone poking me with a cattle prong and cold water running down my back (doesn't actually feel like that but makes you shudder/jump forward like that). I thought it would have calmed down by now (6 weeks) but even last night I was wakened by a feeling lik someone giving me an electric shock. Is that normal? Will it calm down? I didn't have an epidural as such, they had about 6 attemps and I only had one slightly numb thigh.
