I am facing chronic dyspnea for the last 6 years, there were some tests recently diagnosed such as cbc, spirometry, paranasal sinuses, all the reports are normal except serum ige which is 201. I have been advised to take 1.montelukast 10 mg, 2.desloratadine. 05 mg 3.nasal spray. I have continued montelukast for some days but now I left it to take. The problem I am facing has been a matter of constant discomfort. What can I do, how I can get relief from it? Is it anything about asthma or any other.
