Hi,
i have also read your postings regarding the impotence and your
bowel and digestive problems may be related with it.
This may be a very serious health issue due to your congenital
arterial growth that makes your organs to be depleted by the
normal amount of oxygenation in order for you to stay healthy.
Whatever happens, be careful not to believe that this is related
to stress (some doctors say it because they cannot do anything
about it). While taking some antianxiety and antidepressive meds
helps, be aware of the psychiatrists. When your health will deteriorate
so much that you cannot bear it, they will commit you in a psychiatric
hospital where they will not have much help for you.
Good luck!
