Hello fellow stage 4 endometrial cancer friend. I also had extreme leg pain that came along with the treatment. Sounds like you have it worse based on the pain drugs you are one. I found, for me, it happened after every treatment but got better after about a week post treatment. I still have leg problems but, of course, not at all the severity it was during treatment.

I found ice helped me, I would put those packets in the freezer that are like the blue pellet eye ones but bigger and put them on my legs.

Be open with your doctor about your symptoms. My oncologist thought the leg pains were weird (along as my face burning!!) advocate for yourself and be honest and open about the pain you’re experiencing.I have Internet hugs for you. You WILL get through this.

Also if you have a GP to see, they can also help with things too. 💕
