Breaks my heart, these darn seasonal allergies. Some of these guys get it SO bad. It sounds like it could be grass/seasonal/pollen. Steroids are just so awful - but - if it gives him back a quality of life, it's something to consider. I mean, if the steroids help - maybe it's something you give only during the absolute worst months - and during the rest of the months - you build up his immune system. Keep us posted and best of luck.
