Hi
@Binkie4 my understanding is that sticky blood can be caused by several factors, it isn't always lifelong or due to coagulation issues.
It can be a temporary response to low oxygen availability due to 'lifestyle factors' such as heavy smoking or an adaptation to environment like very high altitude. My mother and I have both had high haemoglobin counts after viruses which returned to normal within 3 weeks (separate times, separate viruses, we live at different ends of the UK.)
My high haemoglobin sticky blood coincided which the onset of my orthostatic intolerance in 2010.
My 6 weeks on blood thinners was last year.
I've had many FBCs over the years and my haemoglobin count was only raised once.
I've had many occasions where I've been a bit dehydrated and taking blood has been difficult, but this has never affected my haemoglobin count.
I can't say for certain my head fog clearing was due to the 6 weeks I spent on Fragmin because I was totally unable to stand at the time and the enforced rest and OI avoidance may well have cleared my head. It could have been due to one factor, the other or a combination of both.
I broke one ankle and damaged the ligaments in the other. They wanted to put pins in my spiral fracture so I could bear weight on the cast, but I react to everything, metals, stitches and iodine all cause me MCAS problems. I agreed to 6weeks total non weight bearing to avoid an op and this made me a clotting risk.
Before the accident I wasn't pacing well, too much walking till I was dizzy, standing and doing stuff, just pushing it really.
I've recently started monitoring my heartrate and checking my blood oxygen saturation with a finger tip oximeter, my oxygen levels are very rarely normal they are almost always low. So I guess my sticky blood didn't resolve due to my oxygen saturation returning to normal.
(Also the fragmin did affect my liver function, which seems to happen with MS patients sometimes too. It resolved when I stopped the injections).
