But generally the underarm lumps cause with pain and fever, but you have not mentioned anything similar.3. The other lumps seen in the axillary region are lymph nodal enlargement which will be seen in case of infection in the post-operative site, underlying medical condition infections / inflammation. 4. An ultrasound of the lump will help in analyzing the lump origin and extensions.5. Recommend you to have appointment with your GP and get the needful investigations done. Hope it helps you.
