I was diagnosed with asthma 3 years ago (aged 20), and now I seem to be developing hayfever too. I've never had hayfever before until last summer I started getting watery eyes and nasal issues (alternating between runny nose usually when I went outdoors and blocked up when I was inside). It wasn't awful so I bought over the counter eye drops to try and help the itching/watering and did nothing else about it.
Thins year my eyes are itchy and streaming with water whenever I go out running and my nose is once again really irritating me. It seems much worse than last year and it's beginning to really bother me... I am feeling fuzzy headed and generally a bit miserable. My asthma has (thankfully) remained in control (I'm currently taking symbicort 200/6 2 puffs twice daily, ventolin before exercise and as needed and montelukast 10mg daily)
My question is if I wanted to try antihistamines for what appears to be hayfever, is it normal to just buy them over the counter at a pharmacy or is that something I should see my GP for? I haven't actually been diagnosed with hayfever, I'm just guessing from the symptoms that it's hayfever. I spend a lot of time outdoors as I'm a long-distance runner, and I live in the countryside.
Thanks in advance.
