1 month back I suddenly found blood in my sputum but I don't have any cough and cold. It continues for a week then stopped.Again it has happened to me 2 days back. I have done chest x-ray where it was mentioned that 'Bronchovascular mark is prominent in the lungs field' and also done CBC with ESR westergren where reports were normal where ESR is 38(high) and haemoglobin is low(11.5).And I have a sharpness pain in my chest,back,neck and sometimes in my abdomen also...Is there anything serious???

Based on your symptoms and test results, it is important to address the underlying cause of the blood in your sputum and the chest pain. The prominent bronchovascular mark on your chest x-ray may indicate inflammation or infection in the lungs. To help reduce inflammation and manage any potential infection, I recommend taking a course of antibiotics such as Azithromycin 500mg once daily for 5 days. In addition, the high ESR and low hemoglobin levels suggest possible inflammation in the body and mild anemia. To address this, you can take Ferrous Sulfate 325mg twice daily to help increase your hemoglobin levels and improve your overall health. It is important to follow up with your healthcare provider for further evaluation and management of your symptoms to ensure appropriate treatment and monitoring.
