Short Term Memory Loss
A friend of mine met with a bike accident and has been having some memory issues since then (he was injected with anaesthesia to have stitches on his lips). He cannot recall event of past one month and also seem to have some short term memory loss (Keeps asking, every 5-10 minutes, again how he met with accident). It's been over 12 hours and he still has this issue. Is it something that might have been caused by anaesthesia? What should be the next course of action?
