If I had a chronic disease I would look for information that would help me cure the disease. The easiest way to do this is by researching the disease on the internet, I could even do it, but it could end up collecting incorrect and false information that could make my situation worse. I could find correct information, but this is hard to judge.
To make sure the information was accurate and credible, I would seek medical attention and get information directly from the professional, the doctor, who knows all the conditions related to my illness.
