Hi and welcome to the community.
I have a couple of thoughts, but I am not familiar with homeopathic treatments that really work for most people. Debbie has had success with an allergy treatment. Maybe she will tell you about it.
Do you take NSAID's? NSAID's can trigger asthma. If you are taking them regularly you could be inadvertantly triggering asthma. You might talk to your doctor stopping the NSAID's for a while. If that does help, you should talk to your doctor about Aspirin Exacerbated Respiratory Disease (AERD) and possible treatment for it. I have AERD and was getting sick (taking pred and antibiotics) every 4 weeks before treatment.
Also, albuterol nebs are frequently the most helpful. I would suggest that you try doing a treatment every 3 - 4 hours for a few days to see if you can get out of the cycle.
It may be time for allergy shots. Talk to your doctor about testing and immunotherapy.
Above all, do not give up!! I spent four years getting sick with increasing frequency before my AERD treatment. There are answers for you but you have ot hang in there.
God bless,
Sonya
