Hello, You describe a condition of persistent rhinitis and itching of the ears that is likely to be related. As far as the yellow liquid from inside is concerned, you need to be seen by an ENT specialist to ensure you do not have a ear drum rupture or a middle ear pathology. Allergy testing by skin prick method or specific IgE blood test will be very helpful in delineating the type of allergies. House dust mite, grass or tree pollens, animal dander, molds are all possibilities but would depend on the nature of your work/environment. For now, long acting antihistamines and nasal sprays (steroid) will help but you would need to see a doctor to get these, and try and get the other tests done sometime soon. Thanks.
