Hi, my daughter, 6 years of age, has had inflamed tonsils and high fevers since Sunday. The GP prescribed antibiotic (orelox jnr) and painkiller (mybulen). Child has complained of leg pain since Monday and is unable to walk as she says it s too painful (thighs and calves). The painkiller has no effect on the leg pain, which is consistent. Please advise what this could be.
