I have a numbness, fuzzy feeling in one spot on the right side of my chest near my collar bone. is this possibly something serious? it has been a continuous feeling of numbness/loss of sensation in the same spot for at least 2 weeks since i first noticed

Nerve issue: In the absence of pain, swelling, limitation of motion and respiratory difficulties, most likely you have a localized problem with a small sensory nerve in the skin. At any rate if the symptoms persist for 4 to 6 weeks without resolution, you should get a medical examination.

See doc: See your doctor then they may send you to a specialist to find out the cause.
