I had the same symptoms on anatrzole. Plantar fasciitis on one foot. Stiff fingers and of course the trigger fingers as well. I went off of anatrzole after 6 months. I am not in a good place as my cancer has returned with a vengeance. I do know you should not just suffer the effects. There are multiple other treatment options, but do know that if you just carry on it can be permanent. Talk to your doctor so the side effects can be managed or you can go on a different medication
