Hi Mark,
Welcome to this forum and website. I do hope we are able to help you through the next few weeks and months - at least until you can make some sense of what has happened to you..... the typo in your original post might well have been 'un-imaginable'- when I was first diagnosed in 1998 that was the word that best described the experience.
Nevertheless..... you have been diagnosed with CML, a disease that is very well understood and for the majority is no longer life threatening/limiting, because of the last decades revolution in effective therapy- i.e. the advent of targeted therapies or TKIs (tyrosine kinase inhibitors)- imatinib, nilotinib and dasatinib (plus others in the pipeline).
All the above TKIs work on the same principal- they target the abnormal white cell exclusively, and by inhibiting the abnormal protein that governs the PH+ cell signaling mechanism (a 'fusion' tyrosine kinase called bcr/abl) and switching off the protein production, they cause those kinds of abnormal cells to die (normal cells that do not have the PH chromosome are not affected). Thus the normal white cells are no longer crowed out and are able to increase to effective levels again.
They become the dominant population again over time. You will see the abnormal Ph+ cell population diminish over the next 3- 6 months.... the goal is to get them down do very low 'molecular levels' so that they are no longer able to disrupt the body's normal immune response.
Imatinib side effects:
I too -and most others- experienced the bone pain/ache you describe. For me it lasted exactly 12 weeks and then suddenly disappeared. The intensity of the pain was high at first- at least for the first 8 weeks, but with lots of massage and heat packs it was manageable.
I was diagnosed in accelerated stage so maybe that is why I took longer than others to see this side effect disappear..... but please be assured it will for you too- probably a lot sooner.
The cramping effect seems to be particular to imatinib- rather than the 2nd generation TKIs nilotinib and dasatinib- I have never taken either of the newer drugs but someone else on this forum might be able to confirm whether the cramping side effect is just with imatinib.
I found magnesium to be very effective- and for joint aches and pains in general.... but you have to use it over the long term (at least 3-months before you feel the benefits). You can use the oil and/or take a supplement.
Heat packs are essential for dealing with the more seriously painful muscle cramps- I find the ones that can be heated in the microwave are invaluable- but a hot water bottle is a good option too.
Relaxation/massage is also helpful on many levels....... but that will take time and you need to deal with the shock of diagnosis first.
If you go to the Patient Power Video/You Tube page (menu on left) you will find lots of video interviews with expert clinicians- I have also put a very good presentation at the top, from Carolyn Blasdel who is a very experienced CML nurse practioner. Her presentation covers lots of things to do with managing CML and the side effects from therapy. You might take some time out to watch at least that one.
Maybe its too soon for you to watch the others, at least until you get your head around CML and learn all the terminology.
Try to take things slowly and allow yourself and your family to understand what has happened and take time to adjust.
There is normal life after diagnosis with CML.... believe me.
If you have any questions at all then do not hesitate to ask. CML is a rare disease with an incidence of 1-1.5 per head of population, but there are many of us who have survived in the long term... I myself am 14 years on from initial diagnosis and live an active and normal life.
Take heart, things will not seem so bleak in a month or so.
Best wishes,
Sandy
