Yesterday morning, I woke up with an achy neck and shoulder on my right side. It s a dull ache (pain level 1, if that), but when I press just above my collarbone near the center of my neck, it s more tender there. The ache extends down my right shoulder and up my head behind my ear. Due to several blood cell tests that revealed slightly high platelet counts, I have been diagnosed with thrombocytosis. I have also recently started taking progesterone temporarily until my hysterectomy in November, so blood clotting is a concern, though my doctor wasn t overly concerned because my platelets aren t terribly high (415 in Jan 2015). What are your thoughts?
