I can feel a small lump a little below my collar bone on my right. it is not painful but i can kind of grasp it when pressing into the flesh. i am not sure if it is a knot or something else. not sure what sort of doctor or specialist to check this.

Doctor can check: One's primary care doctor can examine a lump, and of course the rest of the patient's body, and get the whole story behind the lump issue. That's the best way to figure out what the lump is. Usually, if the lump moves in the skin, it probably is a small skin cyst. If the lump is under the skin, and the skin slides over it, it may be a lymph node. There are lots of lymph nodes in the body.
