I have terrible allergies to dust, dander and weeds. Do you have allergies?
Yes, and its so annoying. I hate having allergies, also known as allergic diseases.
In the spring I have to get shots for my alleriges and take prescriptions throughout that season
Me too, if i dont then I get red eyes, an itchy rash, sneezing all day!
I get a sore throat, sneezy runny nose, eyes watering and a headache, its debilitating and the medication makes me sleepy
Their development is due to both genetic and environmental factors, so I think you should try to find out why you get them.
The allergist said its genetic mostly but irritated by environmental factors 
I would recommend further testing of the skin or blood may be useful in narrowing down your allergic trigger.
Medications help a lot but I also removed all carpet and drapes and replaced with tile and blinds, that helped a lot
Thats a good start, I have milk allergy, which is is an adverse immune reaction to milk. I have now stopped drinking milk!
