You should not start antibiotics without consulting a doctor first, as inappropriate use may worsen the infection or lead to antibiotic resistance. For mild symptoms, try soaking your finger in warm water several times a day. If your finger is red, swollen, painful, or has pus, please see a doctor promptly for proper diagnosis and treatment.

If your fever persists after taking Sinarest and Cefran 500 mg, it may be due to a viral or resistant bacterial infection. Stay hydrated, rest, and get a doctor's evaluation for possible blood tests or a change in medication.
