This kind of bump can be a swollen lymph node,a sebaceous cyst or a lipoma. Lymphadenopathy (swollen lymph nodes) is usually caused by a viral or bacterial infection along with other numerous causes.Treatment is usually cold compresses,over the counter anti-inflammatory analgesics(pain killers) like acetaminophen or ibuprofen,antibiotics if cause of infection is suspected to be a bacteria and surgical drainage if there is any abscess formation.
Sebaceous cyst is a closed sac or cyst below the surface of the skin that has a lining that resembles the uppermost part (infundibulum) of a hair follicle and fills with a fatty white, semi-solid material called sebum produced by sebaceous glands of the epidermis.It is usually painless but can become painful if infected.Then antibiotics are needed.
Lipoma is a benign tumor of the fat cells.It is usually self limiting.
Hope it helps.Take care and regards.
I have a bb sized bump sticking out of my right front shoulder. I have history of Basel cell carcinoma removable along with many kerotisis. Short of going to doc, what should I do?
