I have been eating a lot of black and green olives over many months I think I got the flu in early January, 2018. I had fever, coughing, tiredness and aches all over. However, even now in early April, 2018 I still experience a lot of fatigue and shortness of breath. Is there any chance that I have developed an allergy to the olives I have been eating, both green and black, possibly in excess.
