Yes it can. The acid reflux can cause the back of the throat to swell slightly. You need to treat this soon before it gets any worse. Try the otc meds ive suggested for a few days and see if theres any relief. Its also important NOT to eat a few hours before bed, the longer the better so your stomach is empty. Also if you are overweight or have fat around the stomach area, try to lose some as this can cause pressure on the valve in your upper stomach causing hiatus hernia. Hope this helps, good luck
