Welcome to the ehealthforum and I am glad to help you out. From the symptoms it looks like sebaceous cysts. Sebaceous cyst is a closed sac or cyst below the surface of the skin that fills with a white, semi-solid material called sebum produced by sebaceous glands of the epidermis. It is usually painless but can become painful if infected. They are quite harmless and don’t cause any problems unless secondarily infected. A large number of these get healed on their own. A few need surgical removal provided they become quite big.

However, what exactly are thesis this can be diagnosed only after examination of the area. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
