Pain/Pulling in Calf When Stretching Hamstring

Got something kind of odd that I’m wondering if anyone else has experienced and/or has any ideas what might be going on. When I stretch my hamstring, I feel pain in my upper calf, towards the outside, in the same leg. Actually it’s more of a tightness or pulling rather than pain, but it’s definitely noticeable. I had some upper hamstring issues in that leg over a year ago, but the hamstring itself seems pretty good now. I’m able to train and it’s not really hindering anything but it’s just a little concerning that it could be a symptom of a larger problem that if I don’t address will turn into something major. I know everything is connected, but it still seems odd to feel a hamstring stretch in my calf.
