My platelet levels have increased significantly in 6 months since diagnosis in Jan 2012. I now believe that the stress/anxiety has played a big part as no other explanation when for last 10 years they have remained fairly consistent. Nothing else changed in my life apart from knowing I have ET! I am on aspirin but considered 'low risk' so fortunately cons not keen at moment to do anything else! Being 37 I am keen not to start on anything til absolutely necessary. Looking for other ways which might help to keep levels down. Already walk at least 1 hr daily with dogs and have monthly massage. Any advice would be appreciated.
