I suggest you renew your social security and medical insurance first to keep it effective. If you go for surgery, some of the related expenses can be reimbursed by medical insurance, and the part above the hospitalization deductible line can be reimbursed in proportion (the proportion is related to the level of the hospital where you live and the amount of money spent), and self-funded drugs are not reimbursed.

Don't buy reimbursement commercial insurance for this: first, many companies regard intervertebral disc disease as exemption and don't pay compensation; The second reason is that people who have a history of illness and are insured against diseases are usually denied compensation for such diseases.
