Hi, my boyfriend was out all yesterday drinking (approx 12 hours) around 10pm last night he ended up in a fight which resulted in him being kicked to the ground in the head, he was sick all night for around 8 hours, we went to A&E this morning which he had a head scan which was all clear but his blood sugar was very low so had a glucose drip, since leaving the hospital his left hand is tingly like pins and needles constantly, this has been happening for about 2 hours, is this something to worry about or should he be ok ?
