Covid phobia. At 99 something fever.

Doc vishal Ramani is my husband.He will have a video consultation with you. He has read about covid a lot and saw dr kk aggarwal's videos a lot and got under panic that he will have all the worst from covid. I have become positive on 6th may ,nd almost a day or two after ,my husband got it. We had very mild symptoms.i had upper respiratory symptoms and got well.Nd he had no symptoms like cough or cold ..just slight fever 99.he thinks that virus is working silently nd will attack him once.His oxygen saturation is perfect 98 or 99.even after walk test.normal bp.all blood reports including d dimer ,crp,cbc ,IL6 ARE normal. He feels high heart rate whenever he tries to sleep and sometimes otherwise also. He hasn't slept from last 3 days.today complete night he was awake. He took medrol 8 mg once two days back on advice of a doc before the blood reports came.then left it coz it wasn't required.took meftal forte twice for fever which was probably not required at 99 something fever.
