she,
call 911 IMMEDIATELY. you are discribing one of the possible very negative outcomes of an epidural (you mean the dr never told you about this? hmmmmmmmm). in the worst case scenario, you are losing cerebrial spinal fluid and c ould die or become a quadraplegic. makes for a good malpractice case, but i'd really rather be healthy.
get a dr to have a look at the injection site for fluid leakage and have bloodwork done to check for infection. NO, WHAT YOU ARE EXPERIENCEING IS NOT NORMAL. it is potentially life-threatening.
like the cable guy says, "get 'er done!" NOW.
