If you are having what feels like a tight throat, are you having trouble swallowing? If you are having trouble swallowing, see your Doc ASAP.
My Father started with heartburn, hiatal hernia surgery, Reflux, then had trouble chewing things small enough to swallow. Saw the Doc who did an Endodcopy and Xray, he had esphogal cancer (which also turned out to be stomach cancer as well).
Back in the stage leading up to hiatal hernia, he felt like he was having a heart attack 'cause the pain in his chest was so intense when he would swallow, or had just swallowed.
It's on my mind 'cause it is the anniversary of his death. I hate thinking about 'cause it makes me mad. If the first doctor he saw about this heartburn stuff had sit him down and told him, if you are so scared of getting cancer ('cause my mom died of cancer, not stomach or anything, ovarian) stop smoking, stop eating fatty foods, stop drinking so much, eat more fruits and vegetables, if the Doc had only taken the time to sit him down, look him eye to eye, and said, "Your diet is going to lead you right to cancer's door, let's change it now before it becomes an awful problem." I think even he would have made the changes. He would have gripped the whole way, but he would have done it.
Check it out, go to Google, type in Mayo Clinic, search their database for "Hiatal Hernia" you'll see it all, causes, symptoms, diagnostic tests, and treatment. Once you see it there, you'll know it's real.
Best of luck,
