I'm curious about what's going on with my health. I've been experiencing watery eyes, a runny and stuffed nose, body aches, an itchy throat and nose, and headaches that all come on suddenly. I usually take cetirizine, and it seems to clear up these symptoms within a day. But the problem is they keep coming back every couple of weeks or even sooner. Plus, I end up sneezing like 60 to 70 times in a day, which is just exhausting. And these really intense headaches are happening every other day too. Could you help me figure out what might be going on?
