Hello,
Thanks for writing in.
You have reported recurrent low
back pain which now radiates into leg hip and leg, and muscle spasms. Currently, taking muscle relaxers.
Pain worsens straightening the leg from the flexed postion laying supine.
It is important to consider the source of the
pain (hip vs lumbar spine)...perhaps pelvic area too since the spasm feels internal. Your family physician can order hip xray or pelvic ultrasound as needed. This decision depends on the rest of your history and any extra symptoms.
Straightening the leg from flexion not only moves the hip but also increases stress on the lumbar spine so spine
pain and muscle spasm can increase with this maneuver.
You may consider a course of physical therapy and if no change or worsening then do imaging MRI or CT scan.
Analgesics and heat/ice packs may also help with the
pain and spasms. With
back pain, it is important to keep stools soft. Low
back pain and spasms can result from straining during bowel movement.
Take care and keep us posted.
