Hi, I am 29. I had mri on Saturday and it was an hour long. Now today the dull ache in my thigh is really bad its constant. I bee. Taking paracetamol, ibuprofen but not easing off. Feels sore to touch. Knee is swollen so I have iced it and put it up. I am just slightly concerned now. I rnag the secretary this morning to get an update on mri and said scan not come through yet with results but was told I be contacted by a Dr by end of Friday this week. Now should I be worried seems fast?
