Almost 12 months since being diagnosed with ET - currently on 3 Hydrea tablets per day and platelets down to 960 from the original 2000 - no particular side effects. However a couple of days ago I suddenly got a very swollen and painful middle finger - it was very tight and looked blue/black. I'm pretty sure it was not an insect bite or sting as it happened while playing bridge !! Could it have been bleeding into the joint I wonder. Has anyone else had similar - will ask my Haem. next time I see her in a few weeks. It is now back to normal with just a little bruising visible.
