Hey, I had this for months a while back! I would wake up at night and have a lump in the throat when swallowing! It was awful. I was sure I had a tumor in my throat. It came and went. One day, after eating out lunch with the extended fam, I went and took a bath. All of a sudden, while lying in the bath, my throat felt like there was an actual golf ball in it. It made a weird double. Click noise when I swallowed. I demonstrated to my hub and he also thought it was very odd. I ran to urgent care, but after two hours, it had stopped. Saw an ENT soon after who quickly and easily diagnosed me with GERD. That can be treated with meds. Much better than the throat cancer I was scared of. After I knew what the issue was, the lump feeling went away for good!
