Question: hello. For the past year i have had a lot of weird symptoms. It all started with facial flushing that started around the same time every night it is also brought on with exercise, heat , anxiety and sex. i am also getting cystic acne on my shoulders and back which started out of no where a couple of years ago and i am still getting them to this day, they are leaving nasty scars and take a long time to heal. I am also getting joint pains in my chest and my left knee. Also noticed increased hair growth on my upper back and chest. lastly i am getting white hair on my head and in my facial hair. I also find myself waking up in the middle of the night 2 or 3 times to use the washroom. So my question is could this be something hormonal in my body creating all these strange symptoms, my doctor cant seem to figure out what is going on. The only thing i have tested postive for is the ANA blood test and have high kidney function.

thanks for your answer, i have done the 5hiaa test and it came back negative i also did a 24 hour urine test for cortisol also negative my thyroid also seems to be ok according to my blood work. Yes my symptoms are unusual, my main concern is the joint pain flushing and the acne on my shoulders which all arrived at the same time. After all the research i have done it keeps coming up with either cushings syndrome or carcinoid. Now i have done a some of the test for them but they came back negative but i also heard that the 24 urine test are not 100% accurate is this correct and are there any other additional test i can take? Thanks again
