Jean, Thank you for the information. I am not sure if I have had these tests run, I will have to check my blood test results. I think they focus primarily on my hormone levels. What is the treatment for polycythemia vera? I am looking it up as I write this. Regarding raynauds, do you become very weak after taking a shower or bath? I usually have to lay down and get my strength back after I take a shower. If I am in a hurry, I take a cold shower, and suffer:-P. I found this information on PV: What are they treating you with? Well, I just went through 2 years of blood test results and I have not been tested for any of the three. I will ask my PCP about it. I'll have to read more about PV before I can let you know if I find any correlation with pit tumors and hormonal imbalance. Take care. You're in my prayers. Meri |
