<s>[INST] i have just woke up and I have found quiet a big lump under my right armpit hardly touched it and a very thick/solid off white mass of puss at least a tablespoon popped out now it's weaping out a sticky clear liquid and it's quiet painful and it has left a big hole and the lump is about this size of a ping pong ball [/INST] HI. If the swelling has increases during overnight to get transformed into an abscess and got opened up also, this indicates very virulent bacteria. You need to consult the Doctor to get the antibiotic cover for an early and complete recovery.and please apply sterile dressings only. </s>
