My son is six and has ASD. He's not very verbal and not always very co-operative. He's had the same grotty viral cough for a few weeks that everyone around here has had but the GP confirmed on Monday that his chest is clear and now he's finally coughing less than he was. His left eye came up on Monday night like he had viral conjunctivitis and he rubbed it like mad and it looked like he had a black eye (this has happened before with him) but then on Wednesday I noticed that there's an injury just under the eye, a sore crusty patch that's been coming and going but he won't let me get a good look. Today he's developed a problem with his mouth. He's been pulling at his tongue and trying to wipe it on tissues. Amazingly he did stick it out to show me but I couldn't see anything obvious. He hasn't eaten much today which is unusual for him but then I suppose if his mouths sore... Does anyone have any thoughts on what could be going on?
