hi i was just wondering if anyone could give me some advice, 2 weeks ago my 3 yr old sons glands swelled up just undr his ears, they started off small and over the time it has grown triple its size. its only his left side that is swallen. he's not been ill or had a temp at all and they dont hurt him at all, i took him to the doctor and i just felt like he brushed us off as my son wouldnt be examed properly. im not really sure what to do any ideas what it could be or what i could do?
