I'm new to this forum and I've decided to post my questions here because I've been struggling to breathe for 2 months and it's not getting any better. Before I start, I should probably mention that I used to have asthma when I was very little until age 5 and I suffer from allergies. But after that age everything became normal and I never had any asthma attack nor did I need any treatment. I only had trouble breathing after exercise like running but it used to quickly go back to normal without any inhaler. In recent years I noticed that my airways had become more sensitive, for example, smelling perfume or detergent would give me trouble breathing although it still didn't require me taking any medication. But everything changed this February when I got the flu. It just happened out of nowhere and once the infection had taken over my lungs, I would spend hours struggling to breathe, not being able to even leave my bedroom.
This whole time I only had salbutamol to help me through it and it didn't even work most of the time. The second time I saw the doctor he refused to consider that it could be asthma because he saw that my sats were good (99) and the respiratory tests (spirometry) were good and showed I had normal breathing capacity. CT scan and chest x-ray were also good. He then refused to give me any medicine. But I kept feeling worst and even went to the ER once because I couldn't take it anymore and the nebullized me which did work (though my sats were 99 before they nebullized me) and I was fine for a few hours before it all started again. The third time I went to the doctor he finally agreed to give me a medicine called innovair nexthaler and he said that the effects should appear after two weeks of using it. He thinks its anxiety which I know it's not.
My symptoms are tight chest and oppression, feeling like I'm suffocating and sometimes it becomes impossible to take a deep breath. When this happens breathing becomes extremely difficult and I have to struggle to keep breathing and it's exhausting. I normally don't wheeze (my doctor said if there is no wheezing it can't be asthma) except when it becomes too hard to breath I hear a wheezing sound when I exhale. This happens several times during the day in any situation , I often wake up with the tight chest in the morning as if my breathing was blocked. I'm scared and I now feel worried all the time. Even when I start feeling better (and it never lasts very long) I can't enjoy it because I start thinking about the next time it's going to happen to me.
So my questions are :
Is it possible to rule out asthma based on the good sat and spirometry results ?
Is it normal for the salbutamol not to be working ? (sometimes I feel like it works after 30 minutes but I can still feel tight chest and difficulty breathing) ?
If there is little to no wheezing and almost no coughing does it rule out asthma ?
