Hay fever or allergic rhinitis a problem on the Camino de Santiago

The comment was:

It is far too early to be suffering from either pollen or hay allergy but I’m deffinately suffering from something. I think it is because of the very dry weather and when walking off road I am walking on dry leaves, this combined with the pollution from too many fires :!: Just a reminder for any one walking early who may expect to avoid the normal triggers of rhinitis :(
