Had mild lower back , hip (left),and  both leg pain(leg pain since 15 years). On 9/6/17, lowerback and left hip pain was severe to an extent that she couldnot stand erect and had severe difficulties in walking or any movement of that sort. Visited an orthopedic who suggested for MRI. Incidentally found arachnoid cyst at T8-T9 level (without any compressions on the nerve). Took tablets and the doctor suggested for an operation which my mother is unwilling to undergo. The pain fluctuates frequently. Sometimes chronic, sometimes mild and at times nil. The doctor has suggested for epidural injection as well. Now, all of a sudden , left hip pain is severe . The lower back pain is very low.
