Hello, i was away for 2 weeks in africa and came bk on friday. (during my 1st few days in africa i had a minor car accident, hitting my head on the window which caused some swelling which has gone down now)For the last 2 days i have been having bad pressure headacnes at the back of my head, im not sure if this is due to the fact that i had to travel on 3 planes of my return during, due to the lack of sleep over the past week or my malaraia tablets. I have made an appointment with my doctor for first thing tomorrow.can you help at all?
