Depending on what you've done to your back, the massage could aggravate the problem. I would get to the doctor ASAP .
I hurt my back in 1998 playing football. I thought it was just muscular and would go away. It lingered until I graduated. We did a lot of dead lifts and cleans as part of our lifting program and I always just chalked it up to sore muscles..... And as soon as I stopped the heavy lifting, I would be fine. After a graduated, I changed my work out routine and cut out all the super heavy stuff. All seemed well. Well, last year I spent about 2 weeks doing a lot of heavy yard work......woke up for work one Monday morning and was in so much pain I couldn't walk! I went to the doctor who told me that I, at some point, I had fractured my L5 vertebrae. He referred my to a neurologist who told me that the trauma to my vertebrae and the resulting instability caused additional pressure to 2 of my discs causing some moderate bulging. The bulging, along with the bone patches that formed during the fracture healing was causing a few nerves to become inflamed and pinched, including the sciatic. He also told me that this was completely avoidable if I had taken care of it when it happened.
So get to a doctor!!!!! Sorry for the long drawn out horror story, I hope your problem is minor. Mine flared up 3 weeks ago and I haven't been able to ride since. :ugg:
