Hello, Thanks for your query. As you are having allergic asthma, it is quite possible you get frequent attacks of chest pain/tightness due to inflammation of airway tissues. Chest tightness and pain can begin or worsen due to stress, anger, cold air, physical activity, cold and allergies. Some infection like pneumonia may trigger this discomfort. You are advised to avoid such triggers and be compliant with your medication. Pain attacks can be relieved by inhalers and analgesics. You are also inserted Hickman Catheter many times, it can complicate in hemorrhage and pneumothorax during insertion and infection. You are recommended to visit your doctor and have chest x-ray to see disease progression and evaluate any infection. Hope it helps. Take Care!
