I Am A 50 Yr Female Who Has Had A

I am a 50 yr female who has had a uterine ablation. I believe I am perimenopausal but have no real way to tell expect my symptoms which are hot flashes and night sweats. However in the last week, I have been woken up by extreme shaking from running a temp and have chills but sweating so much it has pooled over my closed eyes. Is this also a symptom or could it be something else?
