Tingling feelings are pretty normal. Actually you are tingling all over your body all the time but your mind is not subtle enough to notice it, meditation will enable you to develop that subtlety.
However your wobbilness could have been caused by your breathing to hard or too deeply, if so just relax and breath normally, or as mentioned before maybe you stood up too quickly.
