I Have Recently Been Advised To Take 2 Puffs Of

I have recently been advised to take 2 puffs of ventolin before engaging in exercise due to a slight wheeziness. I was hillwalking on sunday- which I have been doing for 40 years, I forgot to take the ventolin before hand and I felt a tightnesd constriction around my heart. I took 2 puffs of blue vetolin followed by 2 puffs from the brown one and headed slowly downhill, it eased up a bit over time on the way down butdid not go away completely. I have had signs of a viral flu like aches and pains for a couple of months now. What should I do
