i have this lump on the left side of my neck.Its located right under my adams apple, but its above my collar bone.My arms hurt really bad all the time and so do my fingers, my bones also pop alot more than usual. What could this be ? It all started after this lump that I can feel in my neck.
HI. This is most probably a swelling of the thyroid with hyperactivity. This means thyroid is over-active. This causes all the symptoms you have. Get an opinion of your Doctor, go for ultrasonography of the neck and blood tests including those for the thyroid. Proper treatment will cover up everything.
