The lumps that occur on the under arms could be caused by a number of things that include cysts (sacs filled with fluid), infected hair follicles and also maybe swollen sweat glands. However these lumps could also be cancerous, therefore it is important that you seek medical help.
The symptom of the bleeding of the holes under your armpit could also be a misdiagnosed symptom of a staph infection, which occurs as result of poor hygiene. These infections are generally characterized by the formation of red bumps under the skin. As the staph infection proceeds, a whitish tip is formed, from which the pus eventually drains and then bleeds a little. If it is indeed a staph infection then you can remedy it by keeping the infected area clean and dry. You should also use an anti bacterial soap, use a hot compress to relive the pus and then cover it with a bandage to keep it clean. Avoid shaving the infected area. Maintaining a high level of hygiene is essential to prevent a relapse. If these measures do not bring about any change in your problem, it is best that you consult a dermatologist for a more detailed diagnosis.
