While I know you are looking for answerers about this problem online, please know that it is not wise, to try and diagnose a problem only using the internet.

In order to put your mind at ease, you will need to see a doctor. If you have no insurance and this involves the breast, it might be a good idea to contact the American Cancer Society and ask if they can suggest a clinic where you can get a breast exam and probably a mammogram at low or no cost.

Here is a link to the American Cancer Society, if you call, they might be able to help you with a clinic in your area,
