Pulled back muscle not healing

solvig

So, I pulled a muscle in my back on Saturday during my bike ride and I've been laid up ever since. I can barely walk across the room and standing is almost unbearable. I've been putting ice and heat on it along with taking Ibuprofen when it gets really bad. I just don't know why it hasn't healed a bit by now. I've pulled it before and I'm usually able to walk in a day or so, but this time it's just so much worse. I'm getting to my whits end, along with being bored to death laying around the house.

Anyone have any suggestions on something else I can try. I pulled the upper part of my left glutious maximus and it just effects every other part of my back.
