Cd88- metallic taste in my mouth.

I need some advice. I've had a metallic taste in my mouth for the past 2 weeks (give or take a few days) it's not sinus or anything. I'm also on CD88. The past week I've had heart burn. So bad it makes me want to cry. I've been eating tums non stop. I don't want to test. I tested on cd13 and nothing. We've been trying to 1.4 years. After I had my tubes untied. Need a peace of mind. Thanks.
