I have had a history of ITP. Couple of weeks back I had a single red dot on my ankle. I did my blood counts and the platelets were 256K. Now im abroad and again I notice a single red dot on my left thigh.  Also Im very constipated due to change in diet. Dont know im ver worried that it could be a relapse

Summarized question: What causes dot on thigh with history of idiopathic thrombocytopenic purpura?
