<s>[INST] My feet and legs tighten up at night. Ankles turn up and stiff with unbareable pain. Can t stand up and need to massage my legs and ankles It s like every muscle in my feet or legs tighten up. Not cjarlie horse pain!! [/INST] Hi, Thank you for providing the brief history of you. A thorough neuromuscular assessment is advised along with MRI of lumbar spine. As the symptoms make me understand the disruption in the nerve mechanism I will advise to undergo an MRI of lumbar spine to see the soft tissue status. Due to lumbar spine pathology, the nerve of the lower limbs' dysfunction arises so getting the proper diagnosis is advised. Undergoing physical therapy for the same symptoms should help you avoid all these. With learning the proper exercises for strengthening the core, spine, lower limbs should give you the best resultsRegardsJay In Chat Doctor.  </s>
