I'm wondering if it was all the antibiotic I was on?? The nurse had the lab test 2 times and even took a sample from my arm after the neck valve sample showed 6.8 and the arm sample was 6.7...... The nurse today didn't mention me taking anything, so I'm guessing I should talk to Dr McGiffin about it tomorrow, I know I don't want to clot or have a stroke! I want normal blood, wha wha. Yep, I'm whining again!!!!!
