It may be the jolt of the current that may be causing muscle contractions to occur. However since I am unable to see you in person and you have having the symptoms you are, especially in the chest, I highly suggest being seen tonight, just to make sure there was no damage done to the heart at this point. Generally they will monitor you for 24 hours. But once you are seen in the ER, they can do a EKG and any other test that may be helpful.
Generally when one is shocked, they look for burn marks, loss of consciousness which does require immediate care. Some people can handle a shock, while others can't. So if you have never had this tingling before, just to be safe, you should be seen.
