thigh pain after prostate milking

Had my first session with the aneros helix trident last night and today I woke up with pain in the inner part of left thigh. I’m starting to think I may have went a bit overboard with my muscle contractions to have the aneros massage the prostate. I was experimenting as much as I could. After about 2 hours I just finished off by masterbating the ol’ fashion way with it inside.

Has anyone ever felt this kind of pain before?
