<s>[INST] Hi. Im 33 years female. I quit smoking on 31 of december. I have a tingling on my left arm, on my left leg, on my foot and a bit difficult to breath. I dont have a pain in my chest, but its not easy breathing as always. Ive mitral valve prolapse but its a stable condition. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Smokers are at increased risk of bronchitis (inflammation of airways) and bronchitis can cause chest pain and breathing difficulty. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease and treatment is based on severity only. You will need inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone).Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
