<s>[INST] I injured my lower back 2 weeks ago. The pain went into the inner thigh and now extends in part down the inner leg to the foot. I am unable to properly bend the leg, and a dull ache remains in lower back and buttock. Most noticable thing however is swelling of leg and foot and what feels like muscle knots in places where the most intense pain is. Age 40, Average weight/height. [/INST] Welcome to Chat Doctor I have gone through your query and understand your concern. At present, you need analgesic such as ibuprofen for pain relief. Physiotherapy will be helpful. You are also advised to get your vitamin D3 done and if found low you can get vitamin D3 supplements. You can further investigate the case by doing MRI of lumbar spine. Swelling of both foot can be also due to heart related condition, so you can get your heart condition examined. You can discuss with your treating Doctor about it. Hope I have answered your query. If you have any further questions then don't hesitate to writing to us. I will be happy to help you. Wishing you good health. Take care. </s>
