Welcome to the forum. You will get a lot of good answers from everyone here.

As far as being turned down on SSI. I got turned down on SS so many times I finally got the State Rep. involved and he helped me to get it. I sent him a letter explaining what was going on with SS and a copy of my files and I had it within one week. This might be something you think about doing.

It sounds like you are having a very rough time of it. I have the RSD in all of the places you mentioned plus so I do know what you are going through.

There will be others that will come on and give you a warm welcome and some good help soon.
