I got a leg rash after a flight to Thailand from Los Angeles. Happened in a matter of hours. Pain has subsided but not sure if it was allergic reaction or because I was immobile trying to sleep for so long. I am a bigger guy and on high blood pressure medication. Before the rash, I had cold chills on the plane and what felt like a high fever on the first leg of the trip. This rash seemed to happen after the 5 hour second leg. Had trouble sleeping. While I feel better now, I still feel at most times light headed. I don't fly back to LAX for another 5 days. Should I be alright to fly back to Los Angeles and see my doctor when I get there. I have seen all this DVT material on the net which is fairly disconcerting. It has been almost 4 days since I landed when this happened. Any advice would be appreciated.
