FEVER Ofc Night Shift ( June Noon Shift)

On Monday Afternoon I had a very bad headache to an extent that I was not able to handle it and mild fever too. But I was taking rest in the hope that it would become fine. In the evening fever increased, I took Diclomol and took rest but I was not able to sleep entire night. Then at 4:00 am I went to office for work and came back around 8:00 am, I started feeling normal, no fever no headache till 6:00pm. After 6:00 pm the fever was back seemed very high and the bad headache was back again. Around 9:00 pm I visited doctor I had 102F fever, headache, fever and chills, he wrote some solutions and injections that were injected into my body. I started feeling better from thereon, fever gone but the headache is not going. I start feeling it anytime of the day. Even now suddenly I feel a very bad headache for just 10 seconds and then normal, 15 minlateragain there will be a headache wave for 10-15 sec then normal again. I have been advised with tests if it doesn't become normal till tomo
