Can allergies cause this? Fever for four months.

Hello, I'm kitkat and I'm new to this website, so I'm terribly sorry if this doesn't belong here.

Anyway, to get started I'm eighteen-years-old and a senior in high school. My immune system isn't... Quite up to par with most people my age, but I've managed to get by. Anyway, since January I've been running a fever from 99-102 Fahrenheit almost non-stop, every so often its lulled to 98-99, but that only lasts a couple days and my regular body temperature is 97.6. I've been to doctors multiple times and they've said its just a common cold, but I don't think a cold should last four almost five months right? I've been on a bunch of antibiotics and I've been taking advil and tylenol to reduce fever, but even that isn't getting me below a 100 once I'm up and about. My mother wants to bring me back to the doctors tomorrow and I've flat out said it has to be allergies and I don't want to go again. Has anyone here ever had a low-grade semi-long term fever?

Also so additional information:

I'm over weight (working on it.)
My mother smokes
I had received a bad ankle injury around the same time I started running this fever; however, in the xray no breaks were found
Some of my symptoms are fever, fatigue, and irritability.

I believe at this point I must just be allergic to something, but I'm not sure. Any advice and opinions would be welcomed. Thank you very much for your time, I would just agree with going back to the doctors, but its just frustrating to be told its a cold and to repeat the process again.

Fever can be caused by factors outside or inside the body. Microorganisms, including bacteria and parasites, can produce chemical poisons. Both the microorganism and the poisons cause the white blood cells (called monocytes) to produce substances called pyrogens. It's the pyrogens that actually cause the fever.

The body also produces pyrogens in response to infection, inflammation, cancer, or an allergy. Illnesses in which the body's immune system attacks its own tissues (called an autoimmune disease), such as rheumatoid arthritis, can also cause fever. Too much exercise in hot weather, overexposure to sunlight, hormonal problems, or some medications can cause fever, too.



Have you've had a full blood panel to rule out any of these?

Kitkat when I was your age I was also walking around with a 100 temp for months, I went to an allergist and he did a food allergy test on my back by taking extracts of didn't foods that was I was allergic too. I found out the foods i was allergic to and stayed away from them as much as I could. That did help a great deal. I have shot for a year and quit then I tried it again years later for 2 years they made me sicker but everyone is different. The food allergy test was the most helpful. It explained why I was running a temp all the time.

Just a thought...
Maybe your thyroid is off.
