had a lump come up under my arm with pregnancies?

Hi,

Welcome to the ehealthforum and I am really glad to help you out. As described by you, there’s a possibility of it being a lymph node (gland) of the axilla (armpit). It can frequently get enlarged due to any infection of the upper limb (hand, arm or forearm).

These glands usually melt away after sometime. The second possibility is of a boil under the arm. Boils are caused by infection of the hair follicle by staph aureus. Apply warm compresses and topical antibiotics on the boil and keep the area clean.

Drainage of the boil is done only when it becomes soft and forms a head. Take some over the counter pain reliever and consult a doctor for examination and antibiotics prescription. If the symptoms persist then I’ll suggest an FNAC (fine needle aspiration & cytology) of the gland and a mammogram to rule out a growth of the breast.

Please do consult a surgeon for the same as it’s not possible to make a diagnosis online without a physical examination. I sincerely hope that helps. Take care.
