Hi Frank ~ I believe you should either go BACK to the University of Iowa, or find another Neurologist. I think this needs more investigation. Now don't get scared, or anything but I do think it just needs to be looked into.
I doubt seriously that there is any more bleeding, but just to be sure you need to have it looked at. It could be something as simple as scar tissue.
I wish you the very best, Frank -- please let us know what happens, will you? I'd really appreciate it. God bless and please take care. Hugs, Lee
