Hello, I pulled my medical records for the past few years and I have noticed a decline off and on with my Platelet Count. It was 191 4/22/2009, and then it started declinging. The biggest decline was in 5/17/2010 where it was 105. Recently I had blood work done and it was 135. Is this something that I need to worry about? Is it something that seems to be cancer or something of that nature. I have panic attacks severely. I should be taking Zoloft 50mg, but stop over a month ago, and I am a 29 year old female. I have high cholesterol, and low HDL of 27. I have sharp pain in my left arm off and on, and tender stomache, could be due to acid reflux. I had a clean Heart Cath done 11/2009, due to my panic attacks and wanting reassurance. Please let me know if this is something that I should be concerned with.
