Hello Fiona
really sorry to hear you are going through an incredibly frustrating time, I really do feel your pain! I have gone from being able to do tempo runs at 8:30 min mile pace to now struggling to even run a mile.
most of the most severe problems for me have now improved to a point where they are tolerable. I have read on this and other groups that side effects do subside over time but never completely go away.
from information I have read I now take various supplements that appear to have improved my general well being. The major improvement was from taking Calcium and magnesium, due to continually having cramp at night and when swimming. Cramps and muscle spasms are tolerable now but have to be careful with some positions especially when stretching.
I’m also taking Iron with B vitamins
Q10 as I’ve read Imatinib affects heart
Curcumin/Glucosamine for painful leg joints
Im 6 months in and the chronic fatigue and slow recovery time after exercise are still causing problems but do appear to be improving very slowly.
i really do hope things improve for you quickly! 🤞
