Problems, Problems, Problems

So I finally got some pain killers for my back, which has GREATLY improved my ability to function at work.  Now my feet are an issue.  I've got large blisters on my little toes, my arches, and my heels, and now the second toes on both of my feet have developed these weird numb spots.  They aren't callused, they're just numb.  I actually just stuck a needle into one of them because I thought maybe there was a really deep blister, like on my arches, but the needle just kept going in and I didn't feel anything and no liquid came out.  I'm not sure how to fix this.  I ordered some diabetic shoes that have a stretchy toe box, so hopefully those will help.  I also bought some moleskin and blister protector things.  I guess we'll see.

Here's a picture of one of my blisters!  It's huge!
