Hey evening MiaGrace...
It's gratifying to learn that MATES is helping you feel a tad less alone in all of this etc...

. I promise MiaGrace, it will become clearer in time, and I understand that being patient with oneself is not so simple at times like this. However, staying calm & open to learning more is what helped me most, after my diagnosis...
Funny really, I mean the range & gamut of turbulence I put myself through in those earlier stages of coming to understand & accept my MPN.
First, it was total disbelief, (Denial), and really at that juncture I set out to prove a mistake had been made in my diagnosis... and that my Thrombocytosis was simple caused by some other ailment, (virus, infection etc...?) Unfortunately however, & after a few weeks of trying and failing to create an alternative theory... I was eventually proved wrong, and then I became quite depressed...
It's a longer story later I suppose, but the concise version... You see, I had been studying for c. 5-6 yrs at Uni' for a Post I hoped to take up overseas in SE Asia; just a final standard medical test to pass & I would've been jetting away three (3) days later. However, I received a late night call from the Chief Medical Officer on the Sunday night, who informed me of irregularities in my Bloods, & stated further Tests would be required prior to my departure... Fast Forward... My diagnosis was confirmed & I lost my Posting... VERY ANGRY!
After, a prolonged period of self-loathing, bitterness & remorse... I asked myself a simple question: Am I giving up now, or do I want to "Live" for as long as I can?
Shortly after, I learned to
accept my illness, and soon after started this website, that then became a Registered Charity, and I started seriously cycling for MPN Awareness, Research, & my fitness & health of course, (include diet spec's here too). Anyways, I am possibly fitter today in many ways, than I was prior to diagnosis... (?) Definitely feel fitter most of the time... But... I would be false if I said it was all easy as saying than doing... The doing required really hard work, on my part...
Anyways MiaGrace, you have loads of questions, & yes... that is exactly the right thing to do... (in my view...). By learning more about your MPN you will eventually become a lot more comfortable etc... And don't worry, it's all overwhelming and confusing at first... It's like learning to walk all over again really...
Let me see if I can't answer a few of your questions for now anyways...
What symptoms are you experiencing MiaGrace?
MG1. Does being JAK2 positive make a difference in which condition someone is diagnosed with?
A1. JAK2, can be present in any of the Three (3) MPNs. However, one of the other "Driver" mutations, CALR is usually never present in PV. Not 100% sure about MPL, (I think it can be), and there is also a diagnosis known as "Triple Negative" & that is when none of the known "Driver" mutations appear to be present. Finally, there is also one other known as "Unclassifiable" MPN. This is extremely rare however...
Your BMB once completed will possibly answer some questions for you... It might show that you have some scarring of the bone marrow... (?)
As I mentioned previously, they use a scale to measure the scarring, from 0-3 (4 levels) 0 being the most benign & 3 being the heaviest of scarring.
Scarring does not usually indicate PV so much as it may MF. However, true MF would also show up in your WBC, and you said that's normal... so that is a good thing...
It's also important to recall when thinking about MPNs, that they are generally all considered as
"Chronic" illnesses, and most of them graduate quite slowly... Obviously, there are some exceptions...
On our website there are a few Links that will help you understand more about each of the three (3) MPNs, and what helps identify them...
Click on the Menu:
"MPNs What Are They?"
Then you'll see a Drop Down List of the Three (3) MPNs:
https://www.mpn-mate.com/mpns-what-are-they/
Scroll right down on that page & keep reading to learn much more about the Three (x3) known "Driver" mutations, of which JAK2 is one of. The other Two (2) are CALR & MPL. All three mutations activate what is known as the
"JAK-Stat" pathway,. and thereby stimulating the
JAK2 protein which in turn creates an over abundance of mutated copies of our Blood cells.
Generally speaking, (very generally), PV usually shows up because of a High Red Blood Cell (RBC) count. ET a High Blood Platelet count. MF can have a mix of both issues but generally larger immature cells are released into the Blood stream, and these are called, "Blasts Cells". The presence of Blast cells & scarring of the Bone Marrow might indicate MF. However, your MPN specialist will know best once those test results are known etc.
Are you still awaiting a BMB at present? Or have you completed that & now waiting on your results? If so... you will know more very soon MiaGrace...

How was the procedure for you, (if you've had it of course)?
Try not too worry too much, it usually does absolutely no good to do so... Just serves to make oneself more anxious, and for no good reason. When you have your results, you'll know where you stand etc... And that will be very soon now...
From all you have shared thus far, it sounds like you have ET to me. ET can have many unwanted symptoms too... But most of them will disappear by simply taking 100mg of Low Dose Aspirin daily...
Please do stay in touch MiaGrace, and I'm happy to send to my Mobile number by your email if you'd ever like to call... Just let me know ok... It helps to talk at times, and after all... That's why we are here really...

. Katie another MATES member is also usually ok to give out her number if you'd prefer to speak w/ a female etc. I won't be offended in the least should you wish to do so... promise...
Let me know what your specialist says after your results return...
Some times... they may want to start patients on some harder drugs... and if that's the case... There are a few options, and you need NOT be limited to just the one that they always seem to want to roll out first...
Anyways, more about that after you've received your results...
Stay happy, safe & well MiaGrace...
Talk more soon...
