Hello @RussellF
Welcome to the forum, I’m confident you will find it a great place to ask questions and take comfort.
I’m so sorry to learn of your circumstance, I’m sure you have lots of questions regarding this and to that end I have copied in our @BloodCancerUK_Nurses.
There are lots of different posts on the forum, and a good number of them relate to your condition. By typing Myeloproliferative Neoplasm into the search engine at the top it will allow you to go straight to any posts regarding this.
I noted one post refeed to MPN awareness day, and again in confident there lots of other posts not dissimilar that may be a good source of information and somewhere you may choose to engage with others who have the condition.
I can relate to some of the things you refer to, as although I have a different condition (I have Chronic lymphocytic leukaemia (CLL)), it does, I’ve learnt, give many people aches especially in the legs, and beyond this you and I are very similar age and I do go the the gym three times a week.
I hope you find visiting the forum supportive and I hope you take the opportunity to let us know how you get on
Take good care
Mike.
