without the ability to examine this lump first-hand it would be impossible to blindly determine what it is. and it will go away on its own. a description is just not sufficient information to make this important call. yes you most definitely need to see a medical provider in order to get an accurate diagnosis.
what is this large hard dark lump under the skin of my inner thigh? it doesn't hurt but i've had it for like 3 months? . there's an oval hard lump under my skin on my inner thigh farther back so you can't see it if i'm standing it barely sticks out from my skin but is large like wide and long. the skin above its darker than the skin around it (pretty sure not dermatofibroma) i thoughtfrom shaving or my shorts were too tight &were irritating the skin but i've addressed these &it hasnt goneaway. it's too low to be a swollen lymph node. should it go away on its own time if i use neosporinor should i visit a dr.?
