The sore throat is unlikely to be due to thyroxine or Kendra. You should get yourself examined by a physician about your throat. The problem seems to be related to an infection of throat-viralbacterial. You should improve the oral health, brush twice a day and do chlorhexidine mouth gargles thrice a day and avoid eating any edibles during ensuing 2 hours to ensure good germicidal effect of chlorhexidine; Do warm saline gargles after you take anything orally. I hope the advice would be informative and useful for you. Take Care!
