Since I (very probably but not tested) had covid last March, my hayfever has gone into overdrive. Started in mid Feb this year and at the same time I have also developed dizziness or vertigo (can't figure out which!). Spoke to a locum GP who was very disinterested and said you don't get dizziness with hayfever and it's also not listed on the NHS website as a symptom of hayfever but googling brings up quite a few pages of it being listed as a hayfever symptom.
My main symptoms are itchy, swollen and red eyes, sinus pressure (but not congestion) and sneezing.
Just interested to see if other people get dizziness with hayfever too or if someone else might be going on. I have health anxiety so please don't tell me I have something like a brain tumour or I will believe you 😁
