It is hard to suffer from Tom Jones Syndrome. No-one understands!

I get the problem in both legs, but faster and worse in the left.
My usual course with illness is to ignore it until it goes away, but that isn't working, and then some.
I was hoping a Dr. House would post. Not knowing is worrying my wife.

My mother had thyroid problems in later life, and that is checked regularly. I just had a fairly comprehensive blood-test, which showed nothing much, but Judy has filed it, I can't find it, and I don't know if I was tested for diabetes until she comes back. Can't remember anyone who had it.
No family history on both sides of heart problems.
The puzzler is the suddenness. No swellings, No problems at all 'till I walk a little further than usual ( I'm on my feet all day, climbing ladders, fixing houses, but I don't hike or ramble.)    Chris.

P.S. I just fixed an identical problem on my son's car. Partly blocked petrol pipe. But you can always scrap an old car.
