DS 22 months had a low fever since Thursday and a bit of a runny poo but was fairly active. We noticed a spike in temperature over the weekend upto 39 gave calpol and he seemed to get better. Yesterday afternoon he woke up from his nap after which we had a cuddle on the sofa watching tv when he suddenly started shaking uncontrollably, eyes rolling up, body stiff, drool etc , the worst experience ever. Called ambulance and has been kept in hospital overnight. The doctors noticed redness in between his ears and throat but he hasn't had a cold or cough that I noticed. He doesn't have any rashes or any other visible symptoms. He did a urine test that was negative but also got his blood sample for testing, don't know the outcome as yet. Please could someone with a similar experiences let me know if it'a ear infection or possibly some other bacterial infection? I noticed a small white blister in his tongue as well which the doc believes might be viral.
