If you are seriously ill then I must suggest you buy my book

It is also available on kindle and bn and if you want those links let me know.
The reason I say this is because I can tell you basically but there are many protocols to follow such as how to heat the seeds, the precautions, the dosage, etc. You see what I mean?
Taking too much is never advisable. You can take the same dosage as you would for any serious illness which is 3 teaspoons a day with honey or orange juice. The first dosage should be taken 1/2 hour before breakfast, the second in the afternoon and the 3rd before sleeping.
You take 1 tsp of oil and mix it with 1 tsp of honey and take this unless you are diabetic. The oil is more concentrated but the seeds you are more likely to have a pure quality. It is hard to make sure you have the best quality with oil as we are not sure what goes into them.
Black seeds are like vitamins, you must take them for life. So if you stop the protocol, the pain will return. I swear by them and take them all the time. I prefer the oil as it is easier. The oil is 2.5 times stronger than the seeds.
A list of companies that I recommend and some I am affiliated with are at the top of the forum. If you are Muslim let me know too as there are many duas for pain.
I am so sorry you are ill, but remember illness always comes for a reason and we must be patient thru these trials and receive our reward for our patience.
I know it must be frustrating looking for a cure. Sometimes the cure is right in front of your face. Fasting may be what you need to do. Have you tried the Dr. Schultz 5 days liver flush. This can be done with none of his herbal treatments. Just follow his fasting plan, it is quite good. Barefoot can guide you on oj fasting and Dr. Bruess has a 42 day cancer cure that would also work for pain.
Fasting rids the body of toxins and the toxins are what causes many pains. No processing, juicing is good. Something is causing your pain. Have you looked at salt? I find salty foods bother me. Do you eat chocolates or sweets? I see something dark in your system?
Either way I hope you get better and can be rid of this pain.
