Doctor, my son aged 11 years has been getting sinusitis headaches now for quite some time. Last time on March 5, 2011, it was quite severe, and we went to the pediatrician and got treatment - antibiotics and pain killer for a week.. Later after it was over, we went to a homeopathic doctor as he was having some cough and we also mentioned this headaches.. and he is on treatment for that.. Now he is again getting an attack of headache.. What should we give him during these headaches.. or at least for today?
