I am a 26 year old female, and for the last 6 days I've had leg pain. Firstly I thought it might just be pre menstrual cramps but the pain is still there and in different areas of my leg. Sometimes it's near my achilles and sometimes my upper thigh. It's not agony pain but just disomfort. I'm worried it might be early stage of arthritis, is this possible? Does anyone have any suggestions to what it may be? Any doctors hopefully would be helpful but I will be going to the doctor if it continues.
