This is most often caused by unbalanced energy. Try grounding and centering. Sadly a lot of people do not do these on a regular basis. When you do magic, you usually pull energy from one source or another (whether you mean to or not) as a means of boosting your work. Sometimes not all of the energy leaves your body, and you can be left feeling it running through you.
For the person that mentioned getting head aches: Most likely you are overexerting.
Both can be balanced by doing grounding and centering. I personally feel it is good to do this before and after doing any working. Should the tingling continue or become bothersome, speak with a licensed physician. There are a few health issues that can cause it. Not all are a big deal so do not feel to worried about it.
