Thank you for your reply.
I went to my Dr's office to see if there was another Dr on call, there was.
I went to his office and spoke to the secretary and explained to her my situation, since you usually don't get attended if you call days ahead of time for an appointment.
Although the Dr didn't see me, he did change my medication to a less harsh one, claiming that the one I was using was too harsh and is actually not a good inhaler. Within the hour I will have the new medicine/inhaler.
The old one was "Ventolin Cfkvr 200do+in"
I was told if my condition doesn't improve by this evening to go to the Dr on call's office again.
