I have uncontrolled asthma. also, rhinitis and reflux. do the latter conditions contribute to the asthma symptoms? how to manage so it's not a cycle?

Yes: Yes...On all counts. 70% of asthma symptoms are allergen-induced. Start of by seeing a good allergy and asthma specialist. Find out what you are allergic to and then consider allergy shots and medications.

Yes: With all those symptoms complicating each other, i would see an allergist. They are best equipped to consider all of the symptoms and work out a plan to help.
