<s>[INST] I threw my back out a week ago (21 years old) and it's been feeling much, much better. But in the past hour I've felt a little pain around the middle of my back even though the pain had been in my lower back, and I've gotten kind of nauseous. Think there's anything to be concerned about or it's just unrelated? [/INST] Hello, I have studied your case.Medication like methylcobalamine with muscle relaxant and analgesic will reduce  back pain; you can take them consulting your treating doctor.Some exercises which can be done extension exercises, Lying on your stomach flat lift leg 6 inches from ground, do it for other leg.Now lift both hand and leg simultaneously, 6 inch off the ground and stayPosition for around 10 breathes. Core stabilizing spine exercises will help.You may consult physiotherapist for further guidance. He may start TENS, or ultrasound which is helpful in your case.I will advise to check your vit B12 and vit D3 level.Hope this helps. Wish you a speedy recovery.  Take care </s>
