Swollen throbbing ankle with no injury?! Is Endometrin to blame?

Has anyone had a sudden on set of an ankle swollen and in pain for no reason? Mine was fine yesterday even on my walk and last night it started hurting. Today I can barely walk. Feels like I sprained it but I didn’t. 😣

I’m curious if it’s related to Endometrin side effects.

I’ve just starting a 3rd IUI cycle so I was on Endometrin for 2 weeks until my period came so I stopped taking it. I’ve not had anything like this happen though. I’ve had fatigue, acne, irritability and sore boobs from the progesterone but nothing like this.

Has anyone else experienced this?
