Oh man I'm so sorry to hear about your back. I had a herniated disc about 2 years ago and it was so bad that I couldn't walk for 2 weeks. I ended up having to get a cortisone shot into my spine and having physical therapy. I hope you get yourself into the doctor and get it taken care of. Back pain is horrible
Don't worry about exercise while you are injured. I have learned that backs are not something to be messed with, and if it starts hurting, I need to let it rest. Also, sleep with a pillow underneath your knees if you are laying on your back, or between your knees if you are on your side...it takes the pressure off of your spine.
The rest of your week sounds like it had highs and lows.....keep on keepin on.
