<s>[INST] Hello My son whos 13yrs of age has complained of pain in his lower back continuing sometimes to his bottom at times it makes it hard to walk for him pain comes and goes. Is it something I should seek medical emergency care or can I wait to see his Doctor on Tuesday being that Monday is a holiday? [/INST] Hello, Thanks for your query. He might be suffering from Acute mechanical back pain.1. Hard bed rest for 2-3 days3. Hot water fomentation to back 2-3 times a day4. Physiotherapy - Inferential therapy (IT) to his back will help you relieve the pain5. Avoid leaning forward, sitting for prolonged time or lifting heavy weights. These activities can increase his back pain. Even after a week if his pain doesn't gets relieved, better to get him examined by an orthopaedician. He might ask to take a X-ray of back do hope that you have found something helpful, and I will be glad to answer any further query. Take care </s>
