my mum who is 56, did MRI, the result says small amount of opacification of the left mastoid air cells in keeping with mild left mastoiditis, the comment made was left mastoiditis, otherwise normal. she is having constant pain and sometimes untolerable pain at the back of her ear. what is the best cure, she has already taken 7 weeks of antibiotics not regularly but in a weeks gap but the problem still persists. what is the best thing to do IV is not done yet.
