Hi sir, i was vomiting blood and i was only coughing while bleeding and i don't have any fever or chest pain and i did blood test in which blood count was low then i did xray of chest in the report it says mild infiltration in right upper zone?

How much blood? COughing up blood can be an emergency. I wonder if you have TB. There are other reasons for your symptoms. See a doctor

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. Any abnormal bleeding warrants and investigation and it would be prudent to see a doctor. Wish you good health!
