I first developed this 'rash' on holiday in Florida in 1989 and seem to get it now every time I fly anywhere at all or spend a day out walking for long periods after traveling any way. It seems to be triggered by walking a lot on ankles that have been swollen from traveling especially flying. My doctors were mystified and I was sent to a hospital to see a consultant who couldn't offer much help but to tell me it wasn't harmful as when pressed on the colour left the area and you could see the finger prints for a short time. Subsequently one time it was very bad and a doctor thought it was cellulitis and I was given antibiotics but on research cellulitis doesn't fade when pressed. I have had the rash in the USA, Dubai, Spain, Italy and France. I tested out a theory two years ago traveling to Spain and again about a month ago traveling to Italy that I had and it does seem to work if a little uncomfortable for the first day of the trip. I wear compression socks from the minute I leave home and leave them on for the journey and then until the next morning. Any swelling of the ankles has then subsided which I think is the main cause of this. I do bathe my lower legs in water as cold as I can stand every evening too whilst away. On both these trips although I sometimes felt the rash was coming on it never actually did - so after 27 years I think I maybe have the answer!!
I developed the same thing in Italy. I was on a tour where we did a lot of walking. Temperature and humidity were high and the tour guide said she has several people who get this every trip when they get to Italy. Was told by pharmacist over there that it is a circulation problem. There were three or four of us that developed this condition. We were all over 60 years old. I am overweight, but in good health otherwise. Others were normal weight. It is slowly going away. It is not a Disney or Florida thing. Seems heat and standing or walking for long periods of time are the common factors. Not sure you need to rush out to the doc, but probably should mention it at next checkup.
I have been looking this up and I think we have what is called Rosea Pityiasis. Which I did not know about until I looked up my symptoms. I have the rash at the moment. I did get a rash on my arms, back and legs but it has been three months now and I am hoping that in August I will be done with it. I think personally we are being used as guinea pigs, I believe this is man made and we are being deliberately infected. If you look it up it can be man made. Its believed that its related to the Herpes virus. I would have thought that there is a campaign of infecting people in Disney as you have noticed that most of you were at the same place when you noticed the rash. I have been noticing similar situations. I personally think that I have been reinfected on several occasions in different places as I have noticed people with similar symptoms around me at the time of infection. There is a race on at the moment to find a Herpes vaccine and of course they need subjects to inject. It wouldn't surprise me if there has been an increase in Herpes in the years leading up to a vaccine.
Had the same DISNEY rash. It may be the chemicals but I attacked it from the sweat line. Last time I wore Crocs canvas shoes without sox and did not have an issue at all (6 days). Now I was down at Halloween, temps great - low to mid 80's - that may also helped. Just a suggestion.
I walked a lot (about 7 hours) with heavy bags on Friday and Sunday at a large Expo in Anaheim (across from Disneyland), I am also overweight (like 40 lbs over my normal weight).
I was shocked when I took my pants of to find "the rush" a 3 inch red band 2 inches above my ankle and around the leg....
Now.... I have an old injury on that ankle so in addition to "the rush" the ankle was swollen but I could see the beggining of the rush (with much less swelling) on my other leg.
I got a similar thing when flying 10 hours and standing a lot because of airport delays.
I am pretty sure the paramedic that posted on this same thread is on to something...injury to tissue on feet/ ankles, etc...from prolonged walking or being on your feet.
So happy and relieved I found this thread!
Try wearing compression stockings , sounds like a circulation problem .
