Gouse bump on my body since I was a baby how do I get rid?

GOOSE BUMPS. If your goose bumps are on the back of your arms and some on your outer thighs you may have a conditin called keratosis pilaris, also known as red bump disease. Not serious or contagious. Cannot tell you without a photo. There are several over-the-counter lotions for this but first a diagnosis should be made. A dermatologist can tell you in a few minutes what you have.
Can't. I am not aware of any cure for this natural rection, nor is there really a need.
