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.
These deodorants are based on natural products that will work to kill bacteria in the armpit therefore preventing the development of bad odors. The deodorants allow you to sweat and are not acidic or donât contain aluminum. There is therefore no chemical reaction that could cause the development of yellow stains.
Cysts or abscesses under the skin may also produce large, painful lumps in the armpit. These may be caused by shaving or use of antiperspirants (not deodorants). This is most often seen in teens just beginning to shave. Other causes of armpit lumps may include: 1  Cat scratch disease. 2  Lipomas (harmless fatty growths).
