So it started about 3 weeks ago woke up in the middle of the night having shortness of breath. Went to the ER and was told it was possible GERD was sent home with famotidine… a weeks past and was still have SOB everyday. Changed my diet and what I drank and saw little improvement. Fast forward to now I’ve been to the ER around 6 times each because of the shortness of breath and the last two times was also because I felt weak and dizzy. I haven’t been eating much and drinking water so far I’ve lost around 21lbs in 3 weeks. I was also prescribed Sucralfate which I just started taking. But even with all that I’m still having SOB it gets so bad that even walking to the bathroom or taking a shower leaves me breathless. I’ve been staying in bed or in a chair cause moving around starts the SOB, Is this GERD? Am I just tripping? Side note I sometimes feel a little acidic taste in the back of my throat but it’s really really minimal that I only notice because I’m thinking about it. Also I think I might have sleep apnea since I wake up with super dry mouth.
