Your adrenal glands are very important and I agree with the first post you need to go to a doctor. Adrenal glands are located right above your kidneys and they help to keep your kidneys working properlyh among many other vital organs. This is nothing to play around with, please make an appointment with an endocrinologist. You have to have your adrenal glands if they are removed you have to take medication the rest of your life to supplement for the loss of the adrenal glands.
Im quite embarrased to go to the doctor... any suggestions on what it could be? what are the adrenal glands?
I would suggest seeing an endocrinologist. Sounds like something is going on perhaps with your adrenal glands. I'm not a doctor, but purple lines indicate adrenal/cortisol problems.
Wishing you the best.
