The patient
A male patient in his 40s.
The patient’s medical history to date
Three years ago, the patient suddenly developed acute low back pain (a strained back) when standing up from a chair. At that time, he had pain only in the midline of the lower back and could not stand up on his own, but it improved in about 4 days. Since then, he occasionally felt as though it might happen again. Over the past 3 months, the condition has worsened to its current state. For the past several months, he has had low back pain upon waking that prevents him from standing up straight, and turning over in bed is also painful. About a month ago, he jogged lightly for a short distance and experienced pain so severe that he could barely walk. He has not consulted an orthopedic clinic. The pain has eased somewhat, but getting up from lying down is still difficult.

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.
