Detailed Answer:
Hello,
Thanks for posting your query.
I have gone through your query and understand your health concerns ,
Lower back pain is quite COMMON among middle aged individuals. Back muscle strain is one of the MOST common causes of acute to severe lower back pain. Lifting a heavy object, twisting, or a sudden movement can cause muscles or ligaments stretch or develop microscopic tears.

Some other underlying causes like Sciatica, Spondylitis, Lumbar herniated disc, Degenerative disc disease, Isthmic spondylolisthesis etc should be ruled out through clinical examination and radiological investigation (like X- ray, CT scan, Myelogram, MRI etc). Kindly, consult with Orthopedic surgeon regarding this for proper management of the case.

TREATMENT: Some general guidelines can help you to reduce lower back pain. These are as follows:

1) Take adequate bed REST with maintaining posture. Individuals who do not regularly exercise to build strength and flexibility are more likely to experience recurrent or prolonged lower back pain.

2) Alternate Hot water bottle or Ice pack can help to relieve most types of low back pain by reducing inflammation.

3) Non-Steroid Anti-Inflammatory Drugs (NSAIDs) are quite useful to reduce inflammation and back pain. You need proper prescription from your doctor.

4) Exercise for Lower Back Pain : It is a key element of almost any lower back pain treatment plan. You may contact with Physiotherapist regarding this.

It includes 3 components: aerobic conditioning, stretching, and strengthening. The exercises are done through a controlled, progressive program to build more strong and flexible spine.

5) Epidural Steroid Injections - deliver steroids directly into the painful area of the lower back to reduce inflammation. It doesn't heal the components of the back, but often provide enough pain relief to allow patients to move, exercise and heal.
