Hi Dr., my baby girl is 7 months old about 4 weeks ago she was very sick with a viral infection for about 1 week.  A week after the last fever she had a small fever again and at this time i also noticed she developed a peanut size lump between her breast and armpit (closer to armpit).  We called her doc and they didnt seem worried about it said if it got bigger to call back but otherwise theyd look at it at 9 month apt.  Im nervous about what it is because its been about 3-4 now and its not getting any smaller.  Any ideas as to what it could be?  Thanks.

Hi, Dear,Thanks for the query to Chat Doctor. I studied your problem in depth and I understood your concerns. Treatment -In my opinion your 7 MTV baby girl is repeatedly seek and needs care to uplift her general condition by proper diet and medicines from your PCP doctor. The armpit lump is neglected from your doctor as its mostly due to lymphadenitis with viral infections she recently had and would go in next 2 myths time or so. If it still remains and does not grow, it may little more to resolve as she is having weak body defenses. So keep a watch if it grows in number and size. Else forget and wait and watch. Show to ER surgeon if it grows and worries more. So don't build up wrong concepts and create more psychic complications in you which would increase risks and costs to you, but just ask a query to Chat Doctor and be comfortable to resolve your health issues. Welcome for any more query in this regard to Chat Doctor. Write good resume and Click thanks if you feel satisfied with my advice. Have a Good Day. Chat Doctor. N.
