Hi I've been suffering from a blocked nose, sneezing, itchy nose, headadaches/ migraines and now a scratchy dry throat, also its making me feel really tired and want to sleep all the time, sometimes im sleeping 12 to 17 hours because i feel really drained. All of these symptoms have become increasingly worse and persistent for the past few months. I've tried over the counter nasal sprays and medications and they don't really seem to help or solve the problem over the long hall.
