on three occasions in the last 12 months i have noticed a bump on my upper chest just below the collarbone. the bump is soft / spongy and looks like a vein. each time as soon as i press on the bump it goes away, there is also no pain associated.I went to the doctor however they said they could do nothing as it was already gone. I’m a 28 year old male with no other conditions other than some IBS.
I’ve attached pictures. at first i was concerned because i thought it was a lymph node however the fact that it will pop up randomly and rarely, and disapear when i push it makes me doubt that. any help is appreciated
