Nasal Alergy. I wake up from sleep.

From last few 2 - 3 years I am having some issues with my nose. My nose becomes runny everytime I smell some spices or some smell, even a perfume would cause issues. If something physically hits my nose then I start sneezing. Also several times after taking shower, sneezing starts, also it starts if I clean my nose. Several Times I thought that these would go away by itself but it didn't happen. Main problem occurs when I am at my job, it hits me badly in a corporate environment as this problem seems odd to a number of people. I tried several nasal sprays, they work for some hours, but after a duration of 8 - 10 hours again this problem starts. If I would tell you some statistics for a week, my nose is good for about 60% of time but for about 40% time it causes issues, specially after bathing or sometimes even after I wake up from sleep.
