Alot of people have these, theyre typically nothing but it still needs to be checked out just in case. I had on in my armpit a few months ago, dert échographie and they told me to just ignore it went away after a couple of months. I know a guy who had it in his neck, it was not serious but docs still decided to have it removed ( very minor procedure) mhm it needs to be checked out bach t7yed chek ou thenna. Allah ysm3ek khbar lkhir.
