Bad allergies (nasal congestion/itchy eyes/etc) with no relief from daily claritind. what are other options? (shots? prescriptions? anything else?)

Dietary will help: Making sure to hydrate well and cutting out sugars, dairy, sodas, processed foods, desserts will reduce phlegm production. Cut out tobacco, as that can be contributory too. There are eye drops that help reduce allergies but you must see your eye doctor first. Cool compresses are also useful over eyes.

Yes, yes, yes: You should consider consulting an allergist especially if rx nasal spray failed to relieve your symptoms. A board/certified allergist can pinpoint the allergens for you and advise you on avoidance measures as well as options on medications and allergy shots. In the meanwhile, try irrigating your nose with saline daily and see if this helps. A/c will also remove most of the allergens.
