Hi. I'm Aliza, a BC patient and the site's unofficial Medical Librarian. I offer advice (usually non medical [Librarians don't offer medical advice as a matter of professional ethics and well, it's illegal as well. It's practicing medicine sans license]). But I offer referrals to doctors, hospitals/institutions, agencies, etc. and research when required/requested.
Yours is a relatively simple question to answer and there's more than one answer, but I'm going to refer you to an online store called wwwdothealthyfootstoredotcom. I hope you can follow that. I'm sorry I have to list the URL this way but if I list it the normal way, they'll delete it. The store offers a toll free number where you can phone to get advice as they offer all kinds of different socks for all kinds of problem feet, so I suggest you call.
I hope this solves your sock problem and that your diagnosis doesn't turn out to be more serious than what brought you here in the first place. That's enough (more than) to deal with!!
If I can do anything else for you, please don't hesitate to ask. Message me here or email me offsite.
