In recent times I've been developing some breathing difficulty with my allergies, I'll have itchy eyes and a runny nose. It had mainly started around a year or so ago when I had gone to the hospital because I had some bad breathing difficulty one night and had to get nebulized to relieve myself. I had taken some anti biotics and the nebulization for a few days. I sparingly use the nebulizer these days, but only when I find it difficult to breathe. What could be wrong? What can I do about it?
