The patient
A female patient in her 40s.
The patient’s medical history to date
Around October 2023, the patient underwent disc shaving surgery at a nearby hospital for a herniated disc.
In December 2024, while bending over to check on her child in bed, she experienced low back pain. A sacral block injection relieved the pain, so she continued under observation.
However, after about a year, her symptoms worsened — with low back pain, numbness along the back of the right thigh, and numbness from the right knee to the toes.
Symptoms increased when leaning backward.
In September 2025, she received another sacral block injection at a local clinic, but it was ineffective.

Our clinic’s treatment method
Additional information about the Cellgel method we have introduced in this column.
Cost of the Cellgel method: 1,320,000 yen per area (including tax) to 1,760,000 yen per 5 areas (including tax)
Risks and side effects of the Cellgel method: Transient pain may occur after treatment. Nerve damage is not a zero possibility due to the very nature of the treatment, but there have been no reports of damage so far in either report cases or publications. There is a very small possibility of allergic reactions to local anesthetics. Symptoms may temporarily worsen during the first week or two after treatment. This is believed to be due to the decompression effect of the implant, which retracts the surrounding tissues. In addition, if the disc is almost completely collapsed, treatment may be difficult. The doctor hold a consultation with you during your visit to the clinic to determine the best treatment option for your condition.
