After 3 months my underarm bruise & lump biopsy showed malignant melanoma. You need a biopsy.
Hi,
Underarm lumps are axillary lymph nodes which could be enlarged secondary to infection or even trauma. They are usually enlarged when a new deodorant is used, after shaving or waxing the underarm area.
You should refrain from the above for a few days and keep the area clean and apply calamine lotion to help soothe the areas.
The pain could be due to trauma, injury, tight clothes, bad posture, lifting heavy weights, infections of the lymph nodes etc.
You could try some warm compresses and oral pain relief medications and see if it helps with your symptoms.
Let us know if you have any more doubts and keep us posted on how you are doing.
Hope this helps.
Regards.
