I have gone through your query.
Dear severe lower back pain is a common feature experieced by large number of people . Apparently it can be caused by factors such as injury, back strain, arthritis, abuse of the back muscles ,such as from poor posture, a sagging mattress, or ill-fitting shoes , or any of a number of other disorders.
Factors such as stress, overstrain while on work , depression, fear and deep emotions can also play a crucial role. This usually comes due to overstraining of back muscles.
For such condition in my patients I would suggest to do stretchting exercises which involve back bending , Pranayam - deep breathing . Some of the Yogic postures like Setu bandh , Naukaasan Bhujjangasan are some of the few postures also help to strengthen muscls & alley pain .Applying muscle relaxants like Relaxyl for local application. You can also give hot fomentation on back. Rest is also advised for 3 days .
Antioxidants and vitamin C, D in natural form , Sunlight , banana ,lemon juice , Turmeric powder a level spoon with hot milk twice a day for a week is helpful in alleveating pain and inflammation .
Avoid fried ,fast food , tea , coffee , alcohol , sleeplessness , dehyderation , worry , constipation .
prper rest , over use of limbs without a proper rest can lead to wearing out fast
If problem persists ,it is advisale to consult an ortho expert
