What causes coughing sore throat hoarse voice i dont have a fever but last night i started having coughing and i felt i couldnt get a lot of air in my lungs it started off as asthma then turned into coughing what do i have and how can i cure it?

Coughing can be a sign of bronchospasm, just like wheezing. So, if you have asthma and this is a dry cough, it is most likely due to bronchospasm. You can treat it with a bronchodilator as well as steroid inhaler. See your doctor if you need prescriptions for these inhalers. If your shortness of breath increases, go to an ER or urgent care. Good luck!
