Maxidex and numbness and tingling

My doctor added Maxide to lower my blood pressure. He said
it could cause some muscle cramps, if it did, just take half the pill.
I have had hair loss. I have numbness and tingling in my hands , legs and feet usually in the morning, when I wake up.
A couple of days ago, I noticed a red rash on my left ankle. It looks like I have been bitten by something, but it doesn't itch.

I've been using maxide now for over 5 years as a way to keep off unwanted water retention. For the past year I've been experiencing numbness and tingling in my feet and hands which has progressed to severe peripherial neuropathy. In the beginning, it was only brought on while running and I thought it was just a result of my running long distances and perhaps just an electrolite deficiency. I began taking a potassium supplement and continued to run (30- 60 miles per week) without much relief. At this point I am no longer able to run. My arms are numb much of the time and my feet and legs become numb while sitting. I am unable to stop using the drug as I blow up and cannot even wear my own clothes. I have not been able to go off the drug for more than a few days without intolerable side effects. It's changed my life. I'm depressed and frustrated that I can no longer enjoy running which was a major part of my life. Has anyone experienced any similar side effects or have any idea if this condition can be reversed?
