<s>[INST] What is it when suddenly your entire waist is wacked with pain, and attempting to stand you get severe pain also, and sitting is the same. Goes on 24 hours hurting like crazy and sometimes very severe even when sitting? I pray you will be able to enlighten me relevant to the causating factors involved? [/INST] Hi, Thanks for providing the brief history of YouScience you mentioned that the pain is constant, and it is making it difficult to stand, sit, turn etc. you need to first lye down on your stomach and keep a hot water bag wrapped up in a towel to provide deep heating, by which muscle spasm comes down. If you do not have any pain in the hip, thigh, calf or feet than you should not worry much. This kind of pain occurs due to either muscle spasm in the lower back or sacro-iliac-joint dysfunction. Usually it takes 5-7 days for inflammation to come down if proper rest is taken. In case if the symptoms don't come down for a safer side you can take an X-ray or an MRI for finding any soft tissue injuries. If the pain is slowing down then you can proceed to meet a physical therapist who can teach you some core strengthening and spine strengthening exercises which will help you more. Never ignore a simple back pain also, as we never know how big it can be or may become. Sometimes due to ignorance the soft tissue injury becomes big and pain level raises.Also, the core muscles and spine muscles are in constant use all the time and their strength is more important for future to avoid any major injuries. I hope I have answered your query. Feel free for anymore queriesRegardsJay In Chat Doctor.  </s>
