Calcified tissue is difficult to treat. I have my own medical history. Why don't I have regular physical examinations to make myself aware of my illness? I endure these illnesses every year, destroying my body and mind. I admire your bravery, but I feel sorry for your untimely treatment of the disease.
Generally speaking, patients with intervertebral disc have different degrees of calcification risk, but those patients who are treated in time without delaying treatment will avoid this kind of thing. Presumably, you also know that early and early patients are afraid of complications caused by surgery and will choose doctors to treat themselves through minimally invasive treatment.
Your topic is lumbar disc herniation, but the diagnosis made by the doctor after watching the film is calcification, which is not minimally invasive and needs to be removed. This is a good source. Of course, timely treatment is needed, but you can only follow the doctor's advice for such a long time. The so-called bone grafting is to remove the aged intervertebral disc from the degenerated intervertebral disc, and then transplant it with the so-called artificial intervertebral disc (of course, this is a general term, generally called bone grafting). The physical function is to absorb vibration, transmit the force generated from top to bottom or from bottom to top, and play a role in buffering and protecting the spine and brain. However, the 8-year medical history directly led to your affected area not being treated in time, and you didn't take better care of your body.
The cost of this operation should not be tens of thousands, but as long as there is a curable method and hope, I suggest you don't give up and don't lose confidence.
Good luck and get well soon.
