So many good suggestions. I have had a bad back on and off for many years- a combination of an injury and the strain of bending, squatting etc with small children. I would add that I was told recently that it takes 6 weeks for any soft tissue injury to mend. I hurt mine again in late October and it has only just recovered. Moderate exercise,walking, regular rests, painkillers, heatpacks, ice packs all help. One thing I would say if it is recurring, do check your bed. I had to buy a new mattress and a mattress topper, these made a huge difference. My sympathies are with you. It is so debilitating. It makes you feel so old! If it isn't improving you should see your doctor.
