YES !!!!!! Meeeeee!! I was on tamoxifen for 9 mos and one day I felt like I had small golf balls on balls of foot. I can’t wear heels any more or walk barefoot in my apt. Went to podiatrist and he diagnosed me with metatarsalgia , finally after too many side effects , dr took me off. We might try something new in January I am still in pain

I had similar but am not a runner. I’m an outside Walker or treadmill Walker but did it regularly 3-4 times a week. After 5 months on Anastrozole ( started July 2020, metastasis to my bones) I had the same
Thing, feel like plantars fasciitis on my left foot. It is finally better after 10 months but I still have some pain from time to time. Now it is starting on my right foot along the side (different position on the foot but same pain) Ugg! I were Crocs instead of slipper in the house and running shoes with a very cushioned insole and that makes a big difference. I also had some hair loss (I think one person who responded to your message spoke about hair loss) and now in the past three months it is starting to regrow and I have all these new baby hairs so that is encouraging. I think all of those side effects unfortunately are normal. As long as the medication’s are doing what they need to do, and I pray they are, the rest I will manage and I’m sure you were all the same. Stay strong ladies you are warriors!

I’m a walker and was on Anastrozole for 2 years. One day both my feet hurt enough I had to hobble. I thought plantar fasciitis. But in both feet at the same time No. I took a break from med. 2 months now off of med and they seem to be improving. Good luck
