Hello I Have Been Feeling Unwell For About Three Weeks.

Hello I have been feeling unwell for about three weeks. It started a week after I returned from a holiday in Malta.Started as a runny nose, then blocked nose, then coughing, hot and cold but no temperature. I feel more fluey as time goes on and my cough is much worst. while on holiday I was bitten several times by mosquitoes and wonder if this is why I am ill.
