Sore back and pulled groins after Trachelectomy??

I had a trachelectomy last January. As soon as I could walk agian- I noticed my back was extremely tight and sore, and my groins were definitely pulled. I regularly do yoga and work out, I couldn't stretch those legs for weeks. I wondering if this is common? I'm assuming the doc had me in a fairly compromising position with my legs spread way beyond my range of motion for several hours. And lying on a flat hard surface can't be good for your back either. Almost a year later, my back is still very fragile. Anyone else experience this?
