Had a local anesthetic shot (just a numbing shot), my doctor consented for a simple "surgical procedure", all they did was cut me open to drain an abcess and put some packing gauze in it, it was on my bottom and shouldn't have cause me any type of problems with baby, my tummy has been crampy for the last hour and it hurts pretty bad, Alayna's heart rate is still in the 140s where it usually is and she's been very active so I don't think I have anything to worry about, I'm just wondering if anyone else experienced anything like this. Could my tummy be crampy from the shot?
