Is there anything I can do to ease the discomfort and pain from endometriosis?

I have not officially been diagnosed with endometriosis yet as I am waiting on results from my ultrasound.
Judging by the symptoms and sensitivity I have from when my doctor did a pelvic exam, Its most likely that I have early stages.
In the mean time I am told to just wait it out for now, but I have so much discomfort in my lower right side,lower back and legs.
If anyone has any tips of what I can do would be great.
