allergic rhinitis
"Used it for a few months, once every morning. Works great to stop the allergies throughout the day, I've definitely not had the debilitating problems that come through now and again as if I caught a cold, and this definitely stops that from happening. But the piercing headaches are bad after a few minutes, so I have to take ibuprofen to get through it. Then, I am OK through the day, mostly, I can function. But after a while, a couple months, my whole body started to feel numb. Can't feel my back, arms, legs, hands, feet, shoulders, and numb in a way that I am not able to perform athletically. If I get hurt, twist a wrist or pull a muscle I can feel those kinds of things, but for coordination, I felt detached, weak, awful, angry, annoyed."
