I'd like to throw Gary Bowyers name in there, did well at Blackburn who have gone backwards since he left and took Blackpool up when they were in turmoil, and has been on the cusp of the play-offs this season in League one.
Maybe I'm being sentimental but instead of just looking at the benefits/lack of benefits for us, is it not just great to see someone who has a lot of potential back playing football again at a good level given his health problems? It was obviously a serious problem that could have resulted in retirement, why not look on the positive side.
Probably not what you are looking for but I had a machine called SinuPulse that basically relieves and cleans anything that's clogging you up too much in your nasal passages, may be worth a search, helps you feel less stuffy ect ad uses warm salty water.
Otherwise loratadine and Citirizine are useful as antihistamine tablets should you be getting allergy symptoms, one every twenty four hours for a week.
