Before the operation, I would recommend several supplements. You are probably deficient in magnesium, so taking an extra 400 or 500 mg of it would probably help. Taking vitamin D (or getting in the sun, or both) will help. Boron is another mineral that people do not give enough attention to, and is probably deficient in the soil where they grow foods. You will probably need at least 5 to 8 mg to start, building to around 20 mg (one organic apple, grown in perfect conditions, can have as much as 20 mg of boron while one commercially grown one grown in lousy conditions has less than 1/4 mg).
Bear in mind that in countries observing Codex Alimentarius, you may not be able to get these supplements at all (and the food is purposely grown in deficient conditions). In the EU, boron is illegal and they even use Borax Substitute because the actual mineral (which is sodium tetraborate, and about as toxic as regular table salt) is banned. And there are no guarantees--but at least, if you try these, you have a shot at avoiding surgery. And even if you still need it, the chances of a better outcome are improved if these nutrients are abundant in the body. If you live in a country where vitamins and supplements are still legal and they are late on Codex Alimentarius, you can research these nutrients thoroughly online. In the meantime, reducing or eliminating fluoride is important as fluoride makes bone and joint problems worse. Usually, this means adding a fluoride filter on your tap water and/or watching that you do not use fluoridated salt in your food.
