This is Kawaguchi Hidetoshi. This is my humble answer to the question.
SLE (systemic lupus erythematosus)... I didn't know, and I looked it up on the internet for a bit... it's really painful...
It's going to be an intractable disease related to the autoimmune system...
In Buddhism, I will explain that there is always a causal relationship (cause and condition) between things and things.
Although it probably had a cause or predisposition, it did not become apparent for a while, but I think it may have developed due to overlapping triggers of some kind of condition (allergy reasons, infectious diseases, changes in hormonal balance, etc.)...
Once it is clear what caused the cause or condition, I know that treatment/improvement, or overcome/cure is possible by changing the cause and condition.
It seems that steroid administration is essential as an effective treatment... I know it can be painful due to side effects...
Please don't overdo it now, don't be bothered, and be asked for help and support from those around you.
And don't ever give up.
Don't be misled by the words “intractable disease” or “unknown cause.”
By changing the causal relationship to a better one, we will surely be able to hope for better results.
Naturally, the relationship of trust with the attending physician who is the doctor should be placed first and foremost, not to mention studying, gathering information, and analysis about diseases, receiving second opinions if necessary, or being asked for advanced research/medical information from overseas, and receiving advice through peer counseling etc. with people with the same illness, with a strong determination that they will definitely, positively, and always cure them for the better, so don't give up I would like you to team up.
Seizing happiness is also largely up to you. I sincerely pray for improvement, healing, and happiness by coordinating better causes and relationships.
