Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here are my thoughts.
Your daughter is 22 months means almost 2 year old, must be very playful and running, jumping around. It is possible that she got an
injury to the right knee and thus complaining of pain.
I would advise you to take her to the
Pediatrician or preferably to the Orthopedic Surgeon for a proper clinical evaluation and investigations like X-ray if needed; get a prescription based medication. Best not to miss anything at such an young age.
As for the
cold, better to get it treated as may unnecessarily complicate.
Do not treat at home, always consult a Doctor.
Hope I have answered your query.
Let me know if I can assist you further.
