yes you most definitely need to see your doctor so you can be properly examined diagnosed and treated. it would be impossible to determine the nature and significance of this lump based solely on a brief description.
i noticed a small lump in my armpit about a month ago. it has gotten larger and has become painful. . it is now dime sized oval in shape below the hair line. there is a shooting pain from the lump into my shoulder and breast. the pain started yesterday and is getting worse. i have checked for ingrown hair and its not. there is no discoloration and is very tender to touch. should i go see my doctor as soon as possible.
