                        Hi, The other symptoms to look out for are red or  purple spots that do not fade under pressure.  (Put a glass on them and see if they fade)  Drowsiness or confusion, a severe headache,  vomiting and a temperature.  Also a dislike of bright lights.  Hope this has been a help!  Good luck.
