For the past 2 weeks now, I have been getting a terrible pain on the left side of my hip. It is kind of on the hip, top of the thigh, top of the buttock. At first I thought I may have bruised it, but there is no mark and it has been over 2 weeks now and I am really starting to worry.
The pain comes and goes, I am getting it about 3/4 times a day, but each time lasting between 30 - 45 minutes and in this time I can move around and get on with what I am doing, but it just hurts so much. When this pain does come on, I find it really hard to sit down just because it hurts so much, the pain is getting worse.

If anyone knows what it could be I would be so greatful if you were to tell me what you are thinking.

I am 20 years old, I have nothing wrong with me and I work as a office assistant whereby I do do some lifting but not very much.

Thanks
