Have you tried snorting saline solution? Salimar from the chemist sorted out my rhinitis and consequent coughing. It was like a miracle for me.
Yes I use sea salt nasal spray from doctors called Sterimar and follow it with Prevalin spray stops pollens from irritating lining of nose, never without.
Went to see a professor at the hospital and he put me on steroids nasal spray, I ended up with cataracts in both eyes. Apparently the steroid spray has been known to cause them,so I won't use steroids.
Cataracts put paid to my Fell walking and driving for Two and half years because of operation complications,and arthritis in knees set in during this time so all of this due to nasal sprays for allergies.
But I still walk locally with our two pugs so it's not all bad,hoping to go back this year and do aqua aerobics at local baths should help with arthritis. That's me having a moan done ! Enjoy the good weather while we can everyone.K
