Seasonal allergies have been a constant issue my whole life. Most medications I've taken either do not work or make me extremely tired and interfere with my daily activities. I'm interested in home remedies, as I do not have insurance and cannot afford expensive doctor visits and medications. My symptoms are stuffy nose, red and itchy eyes, sore throat, head and body aches and sensitivity to nearly any changes in the atmosphere. These symptoms only occur in the spring/summer months and make it hard to function on a daily basis.
Sorry to hear you're having such a rough time. Unfortunately, there are no home remedies that have proved that effective. Some people are having good luck with nasal saline rinses, and if you do a search here, you'll find a couple of posts I've made on them.
However, it's important not to overdo it on the rinsing, as too frequent use can actually trigger respiratory infections. So go with caution.
Still most home remedies are not harmful, so you might want to experiment with things like yoga, self hypnosis, etc. to see if they help you. You never know!

Allergies are very difficult, especially during the Spring and Summer months. As Kathi stated earlier, many home remedies simply do not prove effective. What I recommend is keeping your environment as clean as possible. "Allergy proofing" your home and avoiding allergens is the to alleviate those unpleasant symptoms. The best place to start is your bedroom , since that is where you sleep and most likely, where you spend the most time.
