Hi,i'm 17 & female, and for the past week or so i've been experiencing moderate pain in my left lower side,it usually just comes between noon-3 and then stays until i go to sleep. But for the past 2/3 days the pain is becoming alot worse,it's really painful and uncomfortable and i've tried taking paracetomol but the pain just comes back after about half an hour. I can't bear this pain any longer.I also have a loss of appetite and occasional sickness.
What could this be,please help i'm worried sick
Thank you.
