[|Human|] My Low Back is chronic and I m wondering if it my psoas muscles in my low back because my back feels very weak after doing sit ups or superman ( lying flat to work the erector muscles ) almost like when I fatigue the large erector outer muscles the strained psoas muscles can t provide proper stability of my lower vertebrae - when I lift my right leg to put on underwear there is a clunk in my low vertebrae and then it feels weak - can you help?
[|AI|]  Welcome to ChatDoctorAfter going through your query I concluded that you need to get following test to know the cause. One is vitamin D3 test as vitamin D3 deficiency is important cause of backache. Second test to perform is MRI scan to know local cause. Till then analgesic such as ibuprofen is helpful for pain relief. Back exercises are helpful. You can discuss with your Doctor about it. Hope your query get answered.
