<human>: Hi, I presently take one half of a Avapro capsule for high blood pressure and 37.5mg of Effexor. I have tingling sensations in my tongue and electric like current in my head, not shocks but like wave of electric currents, it comes and goes, what could be causing this?
<bot>: Hello! Welcome on Chat Doctor! Your symptoms could be related to increased potassium levels. Trigeminal neuralgia can not be excluded either. Are these symptoms triggered by mouth opening or eating? Anyway, I recommend consulting with your attending physician for a physical exam and some tests (potassium plasma levels, complete blood count, PCR, ESR for inflammation). If the above tests result normal, the next step would be performing a brain MRI study. Hope you will find this answer helpful! Kind regards,
