Lately I have been having a strong salty taste in my mouth around my front teeth and the tip of my tongue as well as my lips I also get a very slight numbing sensation on my lips the only thing new that I have noted lately is that I was prescribed a medicine for heartburn and I had to drink contrast dye because I was getting a CT scan of my stomach. My question is has anyone else with this taste recently had a prescription heartburn/reflux medicine or had any medical tests where you had to drink the contrast dye??
