For the last few weeks or so, I've had what feels like a recurring heartburn sensation. My doctor checked me out and said it was probably a muscular strain, but it sure doesn't feel like it. He suggested Aleve, but that didn't work. Also, I've been taking Pepcid on a regular basis for several months now for an unrelated issue*. I'm wondering if that could be working against me, as I'd expect it to reduce the likelihood of heartburn symptoms. Any ideas?

*For what it's worth, I'm not convinced that Pepcid is the proper solution to my other problem, but the specialist who prescribed it believes otherwise.
