I haven't done my back for two days. I feel backache, backache and cold today. I used to have backache because of the weather change. .

The kidney won't hurt. If the kidney hurts, it will be in big trouble. It is estimated that you have low back pain or a cold, so you don't need to be examined. Just buy two pieces of wet and pain-relieving ointment and stick it on it. It is normal for a person to have a slight illness, so there is no need to be nervous, let alone to see a doctor often. Self-care is much better than any hospital. Wish you good health.
