<s>[INST] Hey I was jumping on a trampoline and I was jumping and tried to do a backflip and landed on my knees. And my lower/middle back (lumbar I think its called?) like crunched. It was like my lower back went forward and my upper snapped back and it still hurts in my middle back. I dont know if its serious its just sort of soreness. What do you suggest I do? [/INST] Hello dear, Thank you for sharing your concerns in this website. I understand you are worried, but I would suggest you to calm down and follow these step sim explaining below:It's obvious you have done a muscular straining and probably spinal ligaments straining since you have done an acrobatic movement that has passed your limits. So first I would suggest you to use:- Fetoprotein gel to your affected area of your back to kill the pain and inflammation- Oral painkillers such as ibuprofen of diclofenac if you have severe pain.- Cold compresses first and Warm compresses if more than one day have passed from the injury. Try to reduce the movements of your back and lumbar area for a while of time. If you perform these steps and still you have not any improvement then consult an orthopedist to do further examinations. I hope you will get relief soon. Take care and I wish all the best! Chat Doctor.  </s>
