<s>[INST] Hi, I woke up this morning and my foot was numb. My foot still feels numb ten hours later. When I walk I feel a vibrating/numbness like feeling in my foot. I seems like some bones might be rubbing together every time I move my foot. What can be causing this numbness/ vibrating feeling? [/INST] Hello, As the symptoms of tingling and numbness are related to nerve entrapment anywhere in its course an MRI of the lumbar spine and clinical examination by the physiotherapist is advised.
