, sore throat in a child may be due to viral or bacterial infection. Pain in leg is common in viral infection due to myositis
. Generally leg pain and other symptoms due to viral infection resolve spontaneously over a period of 5-7 days. If pain persists then evaluation will be needed (like muscle enzymes). Consult your physician to evaluate whether this pain is due to arthritis
as in streptococcal sore throat
involvement of joint may also occur.
So I would suggest you to continue with the same medication and to consult your physician for proper clinical evaluation.
