Talk to General Physician on Fever With Shivering And Sweating

I had suffered from COVID in FEB 2021 with symptoms of chills, fever, cough and congestion and got vaccinated with Moderna on 21-Aug-2021. Now after a month on 15 - September - 2021 I again went through fever but there was a cycle that kept on repeat. I woke up early morning due to shivering. I take 2 panadols and shivering is gone but sweating starts. After couple of hours of sweating, i feel myself normal but this normality lasts a couple of hours and i again start shivering. take 2 panadols again, sweats, get normal for few hours but again shivering starts.
