I think the tingling and brain zaps are caused by two different things.
From my experience, I got tingling in my hands and lips when I was low on calcium. Try chewing some Tums and see if that works.
I also get brain zaps on different meds. I never know when or if it will happen, but no doctor has been able to give me a reason. I hate the feeling. I always wondered if I was going to black out or have a seizure but so far (thank God) nothing bad has happened; just a nusance.
