I developed cauda equina lesions immediately following L3-L5 laminectomy w/ dural tear; are there grounds for medical malpractice lawsuit present?

Since my surgery 2 months ago, I have constantly presented perineal stinging/numbness, bladder/bowel difficulties, and increased low-back pain; I've reported these symptoms repeatedly to my surgeon, his P.A., his resident team and all attending nursing staff, etc. during my post-op stay and at subsequent followup appointments with the surgeon. Surgeon team did no diagnostic imaging/testing during my hospital stay. Despite that my symptoms were indicative of serious medical condition of cauda equina, no effort was made to either rule out or confirm its presence - even after my discharge and subsequent return to ER due to pain & discomfort, still no diagnostics were done. Through my persistence, the P.A. wrote a script for MRI & imaging was then done; to date, surgeon team has not reviewed its finding with me. A 2nd opinion I obtained from a local neurologist confirmed presence of cauda equina lesions, and recommends that a neurosurgeon perform decompression at the earliest opportunity.
