What does a pulling feeling in one glute mean when you jump up from laying on your stomach to up on your knees?

As I was laying on my stomach, I jumped up on my hands and knees because I was startled by a centipede. I felt a pull in my right buttock and now feel some soreness there and in the area behind my knee. I have  had increased lower back pain and sciatic pain in my right leg for the past week, so I’m quite worried I just did a doozie, especially since I had already been feeling a bit better today. On the plus side, I don’t feel any sharp or intense pain necessarily. I’d just like to know whether I should be worried about the effects beyond today.
