I could say that I'm experiencing something similar but I've no problem with getting tingling/chills (also very strong if I want to, leading to uncontrollable shaking).
The thing is, I can't feel anything "inside". All the sensations happen on skin only, no matter the concentration etc.
Also, often, some time after the meditation, I feel an intense cold, as if it was inside of me and I do feel cold (even though my skin is warm) and shake wildly as if I was thrown naked into the ice cold water. I just can't controll it and have to wait it out.
I guess that only shows that every single one of us is different and first, we have to explore ourselves.
So cheers and don't let it bother you.
Hail Satan and all the true Gods!
Hail Gods of War!
