I have one bump and one lump under my armpit. The lump is under my skin and can only be felt when touched. My sister and mom said they didnt feel anything though, so I m not worried about the lump. I am worried about the bump though. It s not like an ingrown hair bump that you can just squeeze; this bump looks like a key-loid (sorry dont know how to spell it) or a tiddy, as some ppl call it. When i squeezed it nothing came out nd you can t really squeeze it too well either. I tried sterilized a needle and pocked a hole through it, but only a little blood came out when I squeezed out. I couldnt drain the blood all the way. It seemed like it didn t want to come out. I m only 16. Should I be worried? Is this common? Is there something wrong with me? And do i really need to see a doctor? Please help! Thank you in advance. I really appreciate this website and all your efforts.
