I have had this on and off for several years now, worst case was last year after a long weekend in New York. So bad I had to be taken off the plane in a wheelchair! Have been walking in UK this week and its flared up again, has never made any difference whether I've worn flip flops or boots. Didn't get it in Peru ten years ago in heat and very long walks so think it's getting worse with age. Aloe vera gel has soothed it tremendously.
As you (all) may realize, I've been posting/looking on here fore a few years now. I have tried a whole variety of things with no success.
Considering medical remedies, websites, my skin doctor... nothing worked.
I spent 6 months recording everything I ate, to see if some food was causing it.. Nope.
But over the past year I have been able to figure out what I can do to stave off this "affliction".
This seems to work for me.... you may not achieve my results.
HYDRATION !!!!!!
Stay hydrated... even OVER-hydration... so you have to urinate more frequently... so what... if it can cause this condition to NOT occur.... great !!!!!!
Especially during warm/hot weather... I am on my feet for long periods of time... maybe 4-7 hours... walking, standing, etc. So I ensure I drink a liter of water every hour or 2. Bingo..... in my case... solved. I have not had an occurrence for 8-10 months now.
Am I ever glad I finally figured this out (for me).
Good Luck.
Went for a walk yesterday for 8 miles in quite high temperatures and when I got home I noticed I have a red rash above sock line and under the knee. Quite unslightly and seems to be very hot but after reading the comments realise it is quite common.
Here is what I do for my rash. I wear flip flops when it gets to be about 60. No more rash. I believe the rash has something to do with the restriction of blood flow. With flip flops or sandals that do not restrict blood flow I have no problem with the rash even in 100 degree weather !!! Hope this helps some of you with this problem.
You get leg cramps from dehydration !!!! Try dill pickle juice for leg cramps. I have the RASH but I have found that in warm weather I wear flip flops to take the pressure off blood flow. I believe the rash is caused from a restriction of blood flow so try the flip flops or sandals that do not fit tight.
I have this also. This is what I have found works for me. Even on just the slightest warm days {60} I wear flip flops and my legs do not get the rash. I believe it is caused from the constriction of blood flow-even the slightest pressure around the ankle such as socks. Even if I wear jeans and flip flops I do not get the rash. Sandals are ok as long as they do not restrict blood flow. Try it, it may work for you.
