Try hijama/wet cupping or colon cleansing. You need to detoxify your blood system first, before any medications begin to fully work. You may not need anything else after a hijama treatment of colon cleansing. Hijama treatment is for about an 1hr and results are almost instant. I suffered from all allergies too, and I did the colon cleansing for 20 days which worked but Hijama is more effective, fast and easy, results last longer.
