Thanks for writing to health care magic.
If he is coughing blood then he should be completely examined and investigated. Is there any history of weight loss
You child may require throat swab for culture, CBC, CRP, x ray
chest etc after complete physical examination.
Further treatment should be based on the findings and investigation reports.
Continue to ask further queries as required.
Hope this helps.
