Thyroid

Neck and thyroid ultrasound on 28th january 2021

Tsh 7.37mlu/L, FT4 11.8pmol/L and thyroid peroxide antibiotics 294 October 2020

B12 definitely 

Chest xray in February 2020 came back normal 

I have swelling in neck, trouble with swallowing, weight gain  slightly and lump above collar bone and under chin 

I have back pain lower, pain right side of chest so bad it hurts to touch and  under my ribcage is worse pain 

I am worried that I might have something serious wrong, has anyone had any problem like this
