Thanks for writing in,
Yes, the MRI
findings indicate that you are suffering from Sacroiliitis
along with Canal Stenosis at L2/L3 and Neural foraminal narrowing on both right & left side.
If your backache
is more on morning with stiffness
then Sacroiliitis is the cause.
If your backache increases as you walk for a distance making you to take breaks in between then canal stenosis is the cause.
If your have associated numbness/ pin-pricking sensation in your thigh or leg, it is because of the neural foraminal narrowing.
Depending upon your symptoms the treatment varies.
Cause for Sacroiliitis have to be investigated with few blood tests. Discuss with your doctor and start appropriate treatment.
Till that time - avoid sitting for prolonged time, use hard bed/surface for lying down/sleeping, avoid lifting heavy weights by bending your back. A course of analgesics with/ without muscle relaxant
can relieve your pain for the moment.
Get well soon.
