Checkup Introduction. People make appointments to see their doctor for many different reasons. Some only go to the doctor when they are experiencing a new problem or concern and are looking for a specific diagnosis or treatment. Others see their doctor at more regular intervals for ongoing follow-up of a chronic problem or disease.
Donât blame it on the sunshine. Most people believe these yellow stains are a result of sweat. After all they only occur in the armpit area. In addition to this, they seem to be ubiquitous on summer clothing. It just has to be the sweat that causes it.
Poor hygiene can cause armpit boils because of the dirt that is trapped within the hair follicle. Failure to bathe regularly can cause excess dirt, sweat and bacteria to collect under the armpit, causing a painful boil to appear. The boil may be either red or dark in color and is usually sensitive to the touch. According to the Better Health Channel, armpit boils may occur due to buildup of dead skin cells and bacteria on the skin under the arm.
