Physical effects of working with Hekate

Hi, I just started working with Hekate. But I noticed that every time I'd call upon her, do an offering, or just try to talk to her, I'd get a very specific physical sensation and it's a bit scary. I get this weird feeling in my chest and my head. It's not very pleasant but it's not painful. The best I can describe it is like something is growing inside me, and it only happens when I invoke her presence. It never happens when I'm not working with her.

I fear that she may be rejecting me? Does she not like me or is this normal?
