Thrombocythemia
"I am on Hydrea due to Ediopathic Thrombocytopenia with platelet counts over 2 milion. I am very young (21) and taking Hydrea for 1 year and a half now. 
Though it has sinked my platelets I have recurrent anemia and infections (most recently in the lungs).
In the beginning I was very tired, legs shook, skin would easily bruise, drugged up feeling from time to time, depressive, muscle pain, burning in legs which was severe and decreased after 5 months, brain fog, stomach pain (still common).
Most common symptom would be enlarged spleen with pain.
I&#039;ve had brutal neurological side effects that have been decreasing slowly with time. Nevertheless, Hydrea compared to Anagrelid and Interferon is by far the medicine I tolerate better. "
