What's the adjective for feeling intense cold pain? (while at the dentist)?

Question

What's the adjective for feeling intense cold/pain? (while at the dentist) I hear this all the time when I get a dental cleaning, but I haven't been able to find the word in a dictionary. It roughly sounds like 시릴 수 있어요. ("This might hurt/feel cold.")

Answer 1

Intense pain experienced at the dentist would be considered, among other things, "Agony."
