I will leave it at that right now. Not so hot news from the MRI, something I wasn't expecting....cartilage is completely worn through on my outer left condyle where the tibia connects to the patella, causing swelling and a lesion. This means I am physically not built to run longer distances, which means the marathon is most likely not going to happen. This is all the information I have right now, but I just want to say thank you for all of the support, love, prayers, and healing thoughts - I appreciate every single one.
I am not sure when, but I will fill you in with details as I know them. For now, I can run short, easy runs to my pain tolerance (as I can't do too much more damage at this point), but there are some decisions I have to make, and I need to gather all of the facts and possibilities before I do. I am completely and utterly devastated, confused, mad, relieved, exhausted right now, so I don't have a significant post to write about this at the moment.
Thank you guys, and hopefully I will have more on this soon.
