Essential Thrombocytosis symptoms

Having had high platelets since 2017 and doctors could not find a cause I paid to see a haematologist and I was diagnosed with ET in 2019. With a platelet level of 723 I was put on baby Asprin but unfortunately it did not suit me. I was then put on Clopidogrel but had an allergic reaction to it. I have refused to have a biopsy so far but said I will if levels go over 800. The haematologist made it quite clear that I am at a high risk of having a stroke. So I am taking Arnica homeopathy twice a day to thin the blood which helps the headaches which I have suffered with for years and take 2 paracetamol a day, usually when I wake-up as that’s when I get most headaches and sometimes it is like having a massive hangover. I also get tired and lightheaded and since January I am suffering with constant tingling hands and feet which according to the internet is another side affect. But as of two weeks ago I have tingling lips and tongue which is not listed as a side affect and I am wondering if anyone else also has these symptoms tingling symptoms. Having tried to see a doctor the surgery have said I can have a routine appointment which is weeks away. My doctor has agreed that I have a blood test every 3 months to monitor, at the moment it ranges from 750 to 800. Any advice gratefully received.
