Yes, I have had it, I had an x-ray, nothing wrong with me, a ct scan, nothing wrong with me, exercise advised as it was a pulled muscle so I went to a private clinic and came home with a bunch of exercises all of which just exacerbated the injury because if you fracture the front one, you usually fracture the back one.
In absolute agony and without recourse to any pain relief because there was nothing wrong with me my wonderful doctor sent me for more tests. Eventually because there was nothing wrong with me, she sent me to see a friend of hers who was a doctor in the fracture clinic. "Oh yes he said,it's a clean break but healing now so you don't need any medication. After 5 months I had a result and I was thrilled to bits.
Had I been offered any pain relief I would have gobbled it down but you don't get pain relief for a strained muscle.
The moral of the story is, it will get better, every person takes a different amount of time to heal, don't struggle on, love yourself and I'm sure it won't last as long as mine with all that walking and exercise i was told to do. 3 years on I occasionally get a twinge. I think ive just vented my spleen haha, sorry!
