Top 5 Painful Forearm Lump Causes

  1. 1.Skin Abscess

    A skin abscess is an infection of the deeper skin that's typically due to bacteria seen on the skin. Recently, infections are more frequently caused by Staph. Aureus (puts the "staph" in "staph infections").

    You should visit your primary care physician or an urgent care clinic today or tomorrow. Treatment of an abscess includes incision and drainage. 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.

  3. 3.Boil (Furuncle)

    Boils are infections of a hair follicle that creates a small pocket of inflammation full of pus. It's typically caused by a common bacteria called S. Aureus.

    Boils typically drain by themselves. You can help by putting a warm compress (be careful not to burn yourself). If things don't get better, go see a doctor who might drain it for you.

    A skin abscess is an infection of the deeper skin that's typically due to bacteria seen on the skin. Recently, infections are more frequently caused by Staph. Aureus (puts the "staph" in "staph infections"). If the infection begins to spread, urgent treatment is required.

    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.

    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, freeze, or burn it off.
