When you ask a question, it is automatically distributed to doctors in specific areas of expertise. Doctors participate in their free time and post answers at their discretion, so sometimes it can take several days to receive a reply.
We are unable to guarantee how many doctors will reply to any particular question. The most common reason RealSelf users do not receive a reply is because the question requires an in-person examination to determine the best course of treatment. In addition, photos can increase the chance that you will receive a reply.
Frequently asked questions are also less likely to receive answers, so be sure to browse the list of questions that have already been asked to see if your question has already been posted by someone else.
