I accidentally relapsed with self harm and I've noticed that the forearm/wrist i self-harm on is kind of weak? Like if I hold my phone with my other hand its fine, but when I do the same with the arm I self harm on it gets sore, achey, and grows tired faster. I'm inclined to think that these might be linked but I found nothing on Google when I tried to look up whether this is a common thing that happens.
