<s>[INST] hello sir .. my sister age 23 married suffering from lower back pain . i have taken the X-ray from the hospital and the Impression is shown in that is Loss of normal curvature of the spine - mostly due to para-spinal muscle spasm .... Sir plz tell me is it so serious and what treatment should be given to this disease...? [/INST] Hi. Welcome to Chat Doctor According to your X-ray report it looks like the right diagnosis, as age is 23 years only.  In this age loss of normal curvature is not decorative process, so don't worry.  Due to heavy exercise or weight lifting para spinal muscles get hurt and spasm. Just take muscle relaxant tablets like MySpace or consult your physician and take rest. If she has chronic pain for long duration then we can think for investigation like MRI spine.  Thanking you. </s>
