For about 3 months now I've been having a weird pressure feeling in throat when I swalow saliva also hard to swallow saliva but I can swallow food just fine and I feel it when I take deep breaths to.also throat is feels tight when I look up and move it side to side witch has been freaking me out. The main reason why I think it's cancer is because ive had heart burn since I was 13 I'm now 25 and I read that could cause it does any one have these same symptoms.
