Why do these things happen?

I am writing this blog with a heavy heart. My medical problems are getting ridiculous. I have been diagnosed with Neuropathy and Drop Foot. Which basically means that I have nerve problems and I can't bend my foot upward - so I can't walk right. I have to wear an AFO brace to keep from falling. I have been having test after test but they aren't finding anything else out. My neurologist doesn't know what is causing these problems. My blood tests all came back fine as well. I had an Electromyography last week - which was terribly painful, I had an MRI yesterday, and I have a Lumbar Puncture (yikes) next week. I started physical therapy last week and it seems to be helping. They don't think that it has anything to do with my surgery, but losing 100 pounds in 4 months can cause things to move around and could have put pressure on a nerve or something. Or it could have been caused by me crossing my legs all of the time. Whatever it is, I just hope that they can get rid of it. But I guess it could be worse.......my brothers life long best friend killed his wife and then himself yesterday. RIP Dan and Brandy. Its hard to think about yourself when something like that happens. Well, I guess I am going to sign off for the day. Hopefully my next blog will be more positive.
