Q:

How does a person get a cold sore?

A:

A cold sore, also called a fever blister, happens when an infection breaks out near the mouth that is caused by a virus. The virus is the Herpes Simplex I or II virus, and you can get a cold sore from direct contact with someone who has an outbreak of the virus at that time. There is some new research which shows that the Herpes Simplex virus may be transmitted by someone who has it, even if they aren't having an active outbreak.

Q:

Are there conditions that could lead to greater risk with knee replacement surgery?

A:

There are certain conditions that might lead to poorer outcomes with knee replacement surgery. If your weight can be classified as severe obesity, weight loss might be necessary before knee surgery. Also, if you the bones in your knee are very stiff, or the skin is not optimal around your knee, your chances of a successful surgery might be reduced. Your surgeon will be able to tell you if there are any concerns with going ahead with your knee replacement.

Q:

What to Expect After Laser Treatment for Diabetic Retinopathy

A:

After having laser in the eye, what you can expect is a short period, about 10 to 15 minutes, of discolouration of your vision, which starts out as a purple colour and then slowly fades into a red or pink colour, and eventually becomes normal vision in about 15 minutes.
