Are all lumps easily distinguishable from normal tissue?

I don't know for sure that my new lump is a lump. I feel it more when I'm all soaped up. My Mom just felt it and said it was a rib. I don't think it's a rib. I'm scared. What does my Mom know anyways, she's not a doctor.

I'm scared. I'm thinking of going to the doctor again. I'm going to bring some lotion with me this time so it can be felt better.

I'm a little afraid the doctor will think I'm crazy. I don't trust the ultrasound that didn't show anything.

My Mom just felt me again with the lotion, she said she didn't find anything. Am I just imagining things? She said the "lump" I felt is all over my breast, she said what I'm feeling *are* my breasts. Maybe she's right. My breasts are pretty small. Maybe the lump *is* my breast.

I dunno. Should I still go to the doctor?
