In my right size of neck, when i turn left side, on the SCM muscle there's a seed like hardness inside, no lump/bump/swelling seen on the skin, i was just touching my neck found that, its not present in the left side of neck. I got it checked by a dentist as i visited for some tooth work, he said its fine as it's non palpable nothing to worry. He checked other lymph nodes though nothing was found Is it fine or i should consult an ent? Or should I ignore it. No pain nothing, just when i touch that spot, i feel hard seed like thing(lemon seed size to be exact). Note: Its not on the skin, rather on the scm muscle, and not visible outside at all. Only when touched can be felt.
