Hi there and welcome to MedHelp!
You can post a question to a doctor at any time, and they will answer it the next time they log on. Our doctors don't have a set schedule, so we have no way of predicting when it will get answered.
To start, go to our Forum list -
http://www.medhelp.org/forums/list You will see our Member Communities on the left - these are support and info forums for members to help other members. You should check out the forum that is most appropriate (or just interesting) for you. We have some amazingly intelligent and informed members, so you should be able to get some info and great support from others.
On the right, you will see our Doctor or Expert forum list. Some of these have a fee associated with it, others don't. It looks like you've found one of our Expert forums.
Here are some FAQs that may help you find your way around -
