Patient Stories
What patients say
“For 16 months I suffered immensely from low back pain. I saw countless doctors, had multiple MRI scans, physiotherapy, acupuncture — I tried everything. Every doctor blamed an L4-L5 disc bulge. Dr. Sasidharan carefully assessed my symptoms, concluded they did not fit that at all, and found the real cause. He suggested a targeted injection. Today I am 80% better and back to my daily activities. He saved me from unnecessary surgery, and from ineffective treatments based on mere assumptions.”

“I came to Dr. Sasidharan after six months of severe back ache with radiating sciatica. I had consulted ortho and neuro doctors and tried varma, ayurveda and acupuncture — none of it worked. He gave me a clear picture of the problem and the right solution. I had an endoscopic day-care procedure and was able to walk three hours after surgery, without the radiating pain. Seven days on, I sleep without pain.”
