Hi!!!!I need an additional information regarding your symptoms....want to know if at all you are having chills
along with those mentioned above.A very important information which you have provided is your occupation of an active construction contractor which points towards Legionnaires' disease(a type of pneumonia
). It's possible that the disease may spread when earth containing the bacteria is stirred up at large construction sites.
So if you are getting spikes in the temperature along with the other symptoms then it is suggested to go for:
Blood tests(culture) for the bacteria,a chest X-ray, which doesn't confirm Legionnaires' disease but can show the extent of infection in your lungs,tests on a sample of your sputum or lung tissue,checks your urine for legionella
antigens .These test should rule out if at all you are suffering from it.Quitting cigeratte is always suggested.
