Stretching pain

So when I do a straddle stretch very close to my fullest extent and bend forward, I get this very localized pain in the back of my left hamstring about four inches down from my glutes, it feels relatively close to the skin but still in the muscle. It’s very acute and the closest pain I can think to liken it to is a burn, not like stretching pain at all. I’ve gone easy on the stretching there for two weeks to let it heal, but it’s still present. Advice? Anyone else experience this?
