I have been using two web sites most of the time. One is WebMD and the other is MayoClinic.
Each one has enough information to help you discover what ailment you may actually have, what side affects you may get from the medication you are taking, advice on healthy living and WebMD even has a section on pet health.
The internet is filled with many sites offering similar information, but I find that I have the best luck with these two.
Staying healthy is important and when we need to find an answer quickly, it is great to know that you are only a click or two away.
Where to look: www.WebMD.com and www.MayoClinic.com
