I want to tear My ear off.

[@AstAscend]

It hurts

[@SpyceptModz]

I have it rn and I can't even wear earbuds anymore

[@sams5177]

@@SpyceptModz if u dont mind me asking.... did u end up treating it by any chance? I have it atm and it's so frustrating. I thought it was a pimple at first in the antihelix part of my earlobe but it's been a week or so and nothings changed.

[@SpyceptModz]

@@sams5177 it took 2 weeks to just go away on its own

[@sams5177]

@@SpyceptModz Ok thank you so much for taking the time to even respond. Hopefully it goes away on its own. I thought it might just be a simple pimple lodged in a random spot on my ear. Thanks again for ur help

[@SpyceptModz]

@@sams5177 no problem! If it’s the same thing I had than it’ll go away very soon

[@blasiansierra7567]

this happened to me but on my tragus and I don't have no piercing, but its painful, how do I get rid of it, if not im going to the emergency room and see if they could open my ear and take out whats in there.

[@TehReckfuL]

I have the same thing and it's been on m ear for about a year i think it's best to go in and get it treated because this shit is hard to get rid of.

[@misssunshine2234]

Is there a histolgic difference between this and Polychondritis? I have Psoriasis arthritis.The histologic Report sag’s it’s a chondrodermatis at the anthehelix.(very painful!)

[@JMGardnerMD]

Yes this usually looks different than polychondritis clinically and histologically.

[@misssunshine2234]

@@JMGardnerMD ,i Thank you soooo much.I‘m from Germany and i worked a long time in a histologic Labor.Most of the time i do my cuts at the microtome…In the 90‘,our Labor was the biggest in Germany( Lake of constance).This is the reason for my question.I only believe in microscopic statements!😜
