Do the small bumps/nodules on your chest look like this?
Red moles, or cherry angiomas, are common skin growths that can appear anywhere on the body but grow most often on the chest and back. They are usually found on people aged 30 and older. The collection of small blood vessels inside a cherry angioma give them a reddish appearance. This type of skin growth is typically not a cause for concern unless it bleeds often or changes in size, shape, or color. Consult a dermatologist if you notice any bleeding or changes in appearance.
Hello and welcome to the forum. Thanks for the question. This has been going on a very long time. Indeed, you should check in with your doctor if there have been any changes and in general, an annual physical is a great thing to have. Then you are guided about this and all other health matters annually.
From your description, they are lumps under the skin and painless? Lipomas are a clump of fatty tissue. There can be different benign things this could be. You could have trapped keratin cells. Cysts are another possibility.
I'd get it looked at by a doctor again and preferably a dermatologist. Let us know what they say.
