Hi, Thanks for the follow-up query, Asthma is a chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction and bronchospasm, mostly episodes comes in the night time. Asthma may trigger the oxygen deprivation in tissues by which causing decreasing blood supply,one can have the symptoms of muscle pain or weakness but there is nothing to worry much because it will end with the immediate asthma medications. The chronic inflammation is associated with airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing particularly at night or in the early morning. You must go for spirometry (pulmonary function tests) to measure peak expiratory flow rate and which will help to make a clear diagnosis along with your symptomatology. Treatment is mainly symptomatic which might require inhalational steroids,beta agonists,anticholinergics as MDI or rotahaler as a regular treatment. To decrease the inflammation of bronchi and bronchioles,you might be given oral antihistamines with mast cell stabilizers (montelukast) and steroids (prednisolone) with nebulization and frequently steam inhalation. Regards,
