The pain that doesn't go away

For the past 2 months I have been battling with back pain. it hasn't been good time.
it got better over the weeks but then last week again, somehow it got triggered again and since then I was bed ridden.
I got to understand a few things about why this keeps on coming back. The conclusion that I have come to now is that it is my erector spinae which gets stiff after long continuous walks.
Last time when it happened, it was due to I walked about 13k steps every day in which about 7-8k was done together. This time as well, I did 6k steps when the back wasn't completely healed, next day I sneezed and it got locked again.
The endurance strength of the back needs to be increased. This time: baby steps.
Anyway today after 5 days I was able to stand continuously for 10 mins to make two cups of tea. Until now I could prepare but midway I would have to lie down, take load off the back so that it doesn't become worse again.
Here's to tea...
