Getting advice for a friend
 

This is what she says:

6/10 she had a cough gave her antibiotics and it went away.

6/30 she started intermittently vomiting and not wanting to eat and being lethargic and diarrhea .

She had a blood test done and her liver and kidneys seemed fine.

She had an x ray of her chest and abdomin and they looked normal.

8/15 her cough started coming back and she still has diarrhea.

Any thoughts? Thanks.
