As long as i can remember, around 8 years old. when ever i exercise or hold my breath, a lump appeared on my neck. the lump goes away when my heart rate slows. afterwards i feel lightheaded. i told this to several doctor, they said i was okay. but the last one stated i had a goiter. i won't need surgery to remove it yet. and i need to limit my physical activity.
the question i want to ask, "Is this an abnormal type of goiter" or "am i overly focused about this"
