have had very low back pain for about two weeks now...mostly on left side. Recently most of pain has moved to right buttock, quite severe, specifically when bending backwards.   No initial trauma...started hurting two weeks ago from just bending over and touching my toes! Pain on left side has mostly disappeared. There is also a mild ache center, low back.
Hi, You may have a prolapsed lumbar disc with nerve compression causing sciatica which would be the pain in your buttock. I suggest you take paracetamol and ibuprofen for the pain. Do gentle, low-impact exercising such as swimming or cycling. See a physio for instruction on building muscles to support your lower back. These are simple conservative measures. If these produce no benefit then you may need to consider epidural steroid injections which reduce the inflammation around the nerve root. Chat Doctor.
