I have a follow up question regarding this post. I have the exact same symptoms (lumbar pain R>L) with neck flexion, also increased with activities such as sneezing/coughing. However, instead of having rheumatoid arthritis, I have ehlers danlos syndrome – hypermobility type. I am in the process of getting flexion/extension cervical xrays ordered by my geneticist to r/o cervical instability – could this also be what is causing my lower back pain? So is is actually just referred pain rather than something pathologically wrong with my lower back? No impingement? I have also been wearing an SI belt recently with some relief of symptoms.
Thanks!
