I went to a doctor once to find out what was wrong with me...I had an obvious health problem at the time. The doctor could not diagnose what the problem was. I then decided to go to a Naturopathic Doctor. The naturopathic doctor was open to my suggestions of what was the matter. He then had me hooked up to an I.V. with a natural substance in it and told me what to do when I got home...follow up therapies that I could do to enhance the healing process.
Essentially what I'm saying is go to a Naturopathic Doctor right away...if you can find one on the net that does I.V. hydrogen peroxide therapy and I.V. ozone therapy then all the better (they don't all do these types of therapies). We don't know what's wrong with you, but if it's a clot that is a problem I'm sure they can hook you up to a specific I.V. that will remedy the problem.
What if you are getting arthritis? I.V. hydrogen peroxide therapy helps Arthritis as well. Check I.V. hydrogen peroxide out on Youtube...you will be surprised how much it can be used for.
Maybe your joints are getting out of alignment and you need to realign them with orthotics. Orthotics are one of the fastest ways to get rid of joint pain. You are 54 years old and Arthritis inflammation can come on really fast.
