Top 10 Hand Bump Causes

  1. 1.Skin Cyst

    An epidermoid cyst is a closed sac under the skin filled with a cheese-like or oily material. It is caused by trauma or surgery.

    You do not need treatment for this condition because it is completely benign; however, if the lesion changes at all, a doctor should be consulted. If you would like it removed, a doctor can cut out the cyst.

It is likely you will be prescribed antibiotics as well. Surgery may be required to get rid of the whole abscess after inflammation has died down. Do not drain the abscess yourself.

    You should head to the nearest ER by car since your infection seems like it might be spreading. It is likely that you will be prescribed antibiotics. Surgery may be required to get rid of the whole abscess after the inflammation has died down. Do not drain the abscess yourself.
