HI, Dear, Thanks for the query from you for your painful BB size admit lumps in both the armpits for 1 was time, which was existing for few yrs painlessly.1-I feel concerned that you are serious to know why the 2 armpit lumps are painful over last 1 wk or so?2-In my opinion this tender bilateral armpit lumps are the fibroadenomas and the pains since last 1 wk, is most probably a starting cyclical pain, which were not there for few yrs of these lumps.3-As such these armpit lumps are fibrotic -mastodon cancers as such, but need supervision for suspicious cancerous developments in these lumps in few cases.4-I would advise you not to worry as it's a cyclical change with the fibrotic change and needs follow up and is a benign tumor as such-due to hormonal imbalance during the cyclical changes.5-Hope this would solve your worry of the bilateral armpit painful lumps.6-Wellcome to Chat Doctor for any more query.
