Thanks for writing your query.
After reading your post, I would suggest that you should get yourself clinically examined and investigated.
Following investigations will be helpful :-
1. Complete Blood Count(CBC).
2. General Blood Picture(GBP).
3. Urine examination(Routine/Microscopic and Culture/Sensitivity).
4. Chest X-Ray(PA view).
You can take paracetamol
500 mg for fever
Other medications can be planned according to the reports of the above mentioned tests.
I hope this is helpful to you.
