I collapsed in a store hitting my head ended up with long cut and bruising to head, spent 5 days in hospital. I normally have about 10/12 of Humulin a day but all the time I was in hospital I did not have any or the first 3 days at home as blood glucose was low. However over the last few weeks my blood sugar levels have been out of control and am now taking 32 of Humulin a day. I am not eating any different than before and drinking plenty, has anyone else had problems for concussion or vertigo, many thanks.
