By the way, psychosomatic illness, does not mean you are making it up. If you have a psychosomatic illness, you will feel symptoms of problems that are not really there, but they will seem very real to you. It is also a very difficult problem, because you are not aware that your mind is thinking this problem, but the symptoms show up.
I had some problems in my younger days. It is weird.
Also, this can be caused by depression.
Again good luck
