Symptom narrative

Normally my arm is sore after vaccine- with this one, zero soreness however a few days after vaccine, I developed pain in my lower throat on one side with swallowing. One week later, developed had headache after eating Japanese Natto ( fermented soybeans) then the next day had fever, chills and diarrhea. This resolved after 24 hours. Closer to week 2 post vaccine, developed fever , chills, headache and throat pain with swallowing, tenderness upon palpation on thyroid. Fevers lasted 4 days with chills and elevated heart rate. Saw PCP, ordered blood tests to include TSH and Free T4. Saw ENT , had laryngoscopy which looked good. ENT ordered thyroid ultrasound. So far, as of today, blood work came back low TSH and elevated T4. Diagnosed thus far with subacute thyroiditis. More thyroid labs are being added on and ultrasound is in 3 days.
