The ENT gave you a good spray.
You have to use it for at least a week or two to see noticeable
effect. Continue for a month, then stop for a month, then recycle.
Did the ENT give you an antihistamine, like Mr Docter advised ?
Otherwise, go to any pharmacy and buy a good, non-

like serrapeptase (Danzen), or lysozyme (Neuzyme).
There are many generics. Again, the pharmacist can
advise you.
You may also try another ENT. A good one is
