Hi.
Thanks for your query. 
Read and understood your history of 
sore throat going on for 6 days now. It is painful to swallow and and move the neck.
You also have trouble eating or taking medications like antibiotic for infected toe and it feels like everything gets stuck in the 
esophagus. 
Your classical complete history is suggestive that you may be suffering from GERD, which got enhanced by the medicines and so on. 
I would advise you the following:
-Start taking PPI like 
Pantoprazole,
-Liquid antacid every 3 hours.
-Tablet like 
Domperidone if it suits you.
- Change of the antibiotic and stoppage of all he medicines which enhance the GERD and Throat problems. 
I hope within a few days you will be fine and fit. 
For all this you need a clinical evaluation and examination done by a Doctor and you need a proper prescription. 
Foods : soft bland diet.
Avoid all the foods and beverages.
-Control of the stress and 
anxiety.
I hope this answer helps you.
