@8m5 sciatica is irritation of the sciatic nerve which can be caused by multiple sources. Your question is impossible to answer without knowing the source of the problem. If it is a pelvis alignment problem, PT may help. If it is a nerve entrapment at the spinal root, that would be a question for a spine specialist. If you have lost flexibility due to infrequent physical exercise or poor posture, that may exacerbate it. Your doctors and PT are best equipped to answer what kind of improvement you may achieve through treatments or PT.
