<s>[INST] I have an ongoing problem with the lower part of my back, this ended up going for MRI and still not actualy understand what the problem is. I am 30 years old healthy and have concerns for this pain. Sometimes it feels like someone is stood on my lower back pressing feeling. I Also when i hoover i get cramp in my hands [/INST] Hi,As you are 30 years of young man and as MRI is normal there can not be having any abnormal findings.This seems that this problem might be due to lack of physical exercise giving easily fatigued and strain of muscles.Go for regular exercises like running, jogging, swimming, back extension exercises etc.Take high nourishing diet.Ok and take care. </s>
