Since moving to another state, I have been suffering from seasonal allergies. This is nothing new to me, during the winter time, and now I am wondering if I have year-round seasonal allergies (sounds like an oxymoron!), or if there is something else I am missing/not telling my doctor?

I've been suffering from all the usual symptoms with allergies/cold. My sinusitis met all the signs/symptoms and cleared with antibiotics. I felt better for a month, but still sniffling, etc. I then develop a cold, which turned into bronchitis, which made me extremely tired and (with antibiotics again), was treated effectively. However, since the bronchitis, 4 weeks later, I have not been able to stop coughing. It is now extremely painful to cough, and I now have pleurisy/pleuritis (inflammation of lung cavity wall). So, more drugs, this time cough syrup with codeine for pain/inflammation and steroids for inflammation. I am feeling better, but am wondering: what next?

It was recommended to me to get a complete allergy test workup, as the doctor thinks this is the route cause of all these respiratory illnesses.

My questions are:
1. Am I overlooking anything?
2. Can seasonal allergies really cause all of this, never-ending, mayhem in my body?
3. Have you had allergy testing done? If so, how was it? Do the allergy injections work? What is the effectiveness rate for allergy injections?

thanks!
