Ate tuna sub w kettle p. Chips &banana peppers. I now feel as if something stuck in throat my chest hurts as well. I can breathe fine. Shld I b concerned?

Possible reflux. Try some liquid antacids and see if it helps. If it does, you likely have some reflux and throat spasm from it. If it doesn't help there might be a scratch in your throat from the chip. If it persists an ENT exam would be helpful.
Yes. Sounds possibly like "heartburn" or gastroesophageal reflux which can be relieved with antacid medications like tums, prevacid, zantac (ranitidine). But if you are having chest pains this can also be a more serious symptom which may require you to see a physician immediately.
