Twitching in the lower limbs or upper limbs is common, but not in the lower back.  Might be postural also. Try lying in flat hard couch with pillows resting underneath your thighs n knees.  Avoid strenuous activities for 2 weeks. How about your appetite n numbness/weakness of lower limbs? If your appetite s good n symptoms persists even after 2 weeks, it's advisory to take MRI to rule out tuberculous spondylodiscitis. Thank u
