A bump on my left side neck above collarbone when felt, not swollen. Off & on sharp pain in left ear. Itchy eyes & skin. Muscle pain+twitches, what is it?

Lump on neck. The lump on your neck can be a number of things but could be a swollen lymph node. Did you have any viral illnesses recently or come in contact with a cat that might have scratched you? Itchy eyes are usually a sigh of allergies. If the lump does not go away it needs to be checked by your doctor.
