Thanks for the query.
You should probably get your throat examined by your family physician.
It is common to have injuries in throat from meat and fish bones. Generally it does not get infected and heals easily without any treatment. Sometimes when it gets infected, there will be pain in the throat and the related lymph
nodes. Your injury
probably might have got infected. So you would need some pain killers and antibiotics to prevent further suffering and heal the wound. Please consult your family physician for an examination and treatment.
You can avoid drinking cold
water. Warm saline gargle would help reduce the pain and discomfort.
Hope I have answered your query. Let me know if I can assist you further.
