Stuck-ish?

I was just thinking a couple of days ago that I need to get my second fill pretty soon, but now I am rethinking that. I made something for dinner tonight that we just had last week - I sauteed shrimp and broccoli and tossed it with tortellini and pesto. I served myself about a cup of food. I ate most of the shrimp, some of the broccoli, and about 3 bites of tortellini, and all of a sudden I felt like I had a golf ball stuck in my throat. I wrapped the rest of my dinner up and put it in the fridge for lunch tomorrow.

About 4 hours later, I needed to take some medication that had to be taken with food, so I had a few Triscuits and a spoonful of cottage cheese and took 2 pills. I have that golf ball feeling again and heartburn on top of it.

I'm trying to figure out what's causing this. Not that it really matters, I just need to respect it and take it easy on the food for now, but I'm finding the whole thing very interesting. Before this, I haven't had any stuck episodes, PB's, vomiting, or intolerance to any food. I can eat bread, salad, any vegetables, steak, and dry chicken with no problem.

I'm on antibiotics and painkillers because I had an abscess on my, um, let's just say upper leg region (yuck and ouch) so I'm thinking my newfound stucky-ness is either:

a) the stress from being in pain for a few days

b) the antibiotics

c) the painkillers

d) lack of sleep from tossing and turning all night last night

e) my fill just finally kicked in for real

I know you're not supposed to take antacids with antibiotics but damn I don't know how I'm going to go to sleep with this burny feeling in my throat, and I'm all hopped up on Vicodin so I need to go to bed soon.
