Only members respond here as nursegirl said, the doctors do not. Some members do have medical knowledge and can advise but for a proper diagnosis you need to see your medical practioner. Just a repeat of the above really.
they do respond to questions here
Hello and welcome!
This is a member to member community, so while you will get great info and support here, no you won't get any kind of clarification from a doctor.
Medhelp DOES have expert forums, however and you can post your question there if you would like an answer from a doc. Go to the main page, and on the right will be the listing of all of the expert forums. There is a small fee associated with that service.
Just keep in mind, that even answers from a doctor is still not a substitute for real IN PERSON care from your medical professional.
