About three months ago I carried a heavy object upstairs and had lower abdominal pain following this.  I recovered from this but find I have a localized pain in the left lower quadrant of the pelvic area that is painful when walking.  I have been examined with no obvious hernia.
Hello, I have studied your case. Due to lifting of heavy weight there can be injury to vertebra or sacrum, you may need to do X-ray spine and MRI spine. Due to compression of this nerve root there is back pain and pain in pelvis. For these symptoms analgesic and neurotrophic medication can be started. Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help. Physiotherapy like ultrasound and inferential therapy will give quick relief. Core stabilizing spine exercises will help. I will advise checking your it B12 and it D3 level. If not relieved ultrasound pelvis may be required. Hope this answers your query.
