Welcome to HCM,
In viral infection ronchi or crepetatons sounds can be heard so nothing to worry.
As infection clears it will be alright.
But as you have tender lymph
nodes in your armpit and get some pain in the breast require evaluation.
Consult surgeon and get your breast thoroughly examined to rule out any lump or other pathology.
It is advisable to go for Mammography
Ok and bye.
