Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Leg weakness on both sides is not a typical manifestation of stroke. The fact that it has been of a progressive nature reinforces that as stroke normally manifests in an abrupt manner. That doesn t mean that it isn t due to a neurological issue though. It may be a manifestation of peripheral nerve or spinal cord conditions. In order to make a diagnosis a physical exam to check for accompanying signs such as altered reflexes, atrophy etc as well as tests like imaging and nerve conduction studies are necessary. So a neurological consult is advised. Hope I have answered your query. Let me know if I can assist you further.
