I am so sorry to hear about your serious illness and how it was diagnosed.

Thank you for taking the time to detail it and place it here as a warning to everyone on this site.

I too have these ridges and wondered what they were caused from.

I'm five years older than you.  What a terrible shock you must have received.  How are you doing now?  If you ever need to email me, please feel free.  jeweldee@xnets.co.za.  I'd be happy to keep in touch with you and offer what support I can.

One never knows what tomorrow will bring, do we?
