If you haven't been sick in a year, ex. Fever, cold. Does it mean you're healthy?

If you haven't been sick in a year, ex. Fever, cold. Does it mean you're healthy?

No but: Some diseases may not cause symptoms until the late stage- you must heard of otherwise healthy people who have a heart attack while jogging. Certain cancers may take months or years to cause symptoms. On the other hand, in the absence of any strong family history of cancer and feeling good otherwise, I won't lose sleep over it especially at your age. Enjoy life. ...Read more

I just developed fever 100.5.I was fine before that. No other symptoms. What is it!? By the way I never have fever even when I'm sick.

Wait & see: I don't tell patients they have a fever unless their temp is over 101. Small elevations in body temperature can have any number of causes, from minor viral infections to over-exertion or over-exposure to heat. Keep an eye on your temp and try to stay cool; if your temperature continues to rise, then you need to see your dr. ...Read more

For what reason do I feel way more sick now that my fever has broke?

Fevers go up N down: Just because ur fever 'broke' doesn't mean for sure that you're in the clear. You need to listen to your body and rest. Keep the chicken soup/fluids going.

I've been sick for 2 days now woth fever and headaches that won't go away. What should I take?

Fever & headache: As long as the fever is not high (persistently > 102), and if it has only been 2 days, I would just take Ibuprofen (otc), 3 tabs 3 times a day as this is probably a viral process that will go away by itself. I would wait up to a week for low-grade fever and mild to moderate headache to go away on its own. If the fever is high, or if the headache is unusually severe, you should see a doctor. ...Read more
