Hello,
Welcome to HCM.
High fever,dizziness,fatigue,nausea with chills could be indicative of some generalized viral infection or might be bacterial infection.
But it must be further evaluated by clinical examination and some relevant tests.
You should go for some routine blood works,ESR,urine examination for routine and blood electrolytes (sodium,potassium) even though you are feeling a lot better now.
You may take over the counter pain killers and anti-pyretics like
tylenol or
ibuprofen along with antihistamines like
cetrizine 10 mg for symptomatic relief from your these symptoms.
Also,take plenty of water with fruit juices for faster recovery and for symptomatic relief.
But the important thing is to rule out infective component by clinical examination and above mentioned investigations since you still feel
mild dizziness and fever.
For that,you may need to see some local physician or visit ER who will know about it and may order prescription.
If there is some infection detected,then he/she will prescribe you appropriate antibiotic course like 3 or 5 days as per severity of symptoms.
Hope this will help you.
Regards,
