Hello, The commonest cause of lower back pain is a torn or pulled muscle or ligament. It is caused by muscle sprains or strains due to sudden movements or poor body mechanics while lifting heavy objects or poor posture. Medical conditions causing such symptoms are spinal stenosis, slip discs, sciatica, degenerative disc disease, ruptured or herniated disc, cancer of spinal cord, etc. You are suggested to get clinically examined by an Orthopedics. Get blood tests, urinalysis and imaging tests done, you will be treated accordingly. In the meantime for relieve you can take Combiflam, one SOS when required. Do not do stressful exercises or stretching exercises that strain your spine. Gentle massage and warm compression may be helpful. Give rest but stay adequately active. Take food rich in calcium, minerals and proteins. If obese, reduce your weight. Take care. Hope I have answered your question. Let me know if I can assist you further.
