Been having a metallic bitter taste in mouth and around lips sometimes what could it been? been 5 days already no medication had hsg done 2wk ago

MEDICATION?: WHAT KIND OF MEDICATION IS IT, CHECK WITH YOUR DOCTOR IF YOU CAN STOP IT FOR 3 DAYS AND THE PAIN DISAPPEARS

Metallic taste: Often from gum infection/bleeding. When was your last Dental Examination/professional cleaning? Can also be caused by GERD, diabetes, and other systemic problems. Start with evaluation of the most common cause. See your Dentist.
