That sounds like quite an uncomfortable situation. You might want to ask your doctor for a referral for a videoflouroscopy ….often called a barium swallow. By having your ability to swallow evaluated using different food and liquid consistencies, they might be able to see if there is a structural issue. The findings might suggest treatment from a speech and language pathologist who specializes in swallowing/strokes. Therapy can include simple exercises to strengthen the musculature to stretch and strengthen your neck. The exercises can be done on your own, however the therapy can be set up around your schedule. Since your issues revolve around the voice and swallowing, you would probably do best with a referral from your surgeon and and find a Speech and Language Pathologist through the hospital….the SLP field is broad so you would want someone who has most of their caseload focusing on this area. There are other avenues you might also need to explore, however the videoflouroscopy is like an X-ray….quick and the results are reported immediately; and therapy with an SLP to develop the muscles can really help. Good Luck!
