I have a pea sized, firm lump inside my earlobe on my right ear, easily movable, no pain or symptoms, has remained and not changed in 5 months roughly. i have moderate health anxiety and i am just curious if its something worth the concern?

See below : Most common cause of such benign lumps involving the ear lobe are either an epidermoid or a sebaceous cyst. Sometimes these will resolve with time or by applying moist heat for 15 minutes 2-3 times daily. If they persist or become bothersome, treatment options include needle injection of an anti-inflammatory medication vs incision and drainage vs surgical excision. If concerned, see an ENT MD.
