Hot Flashes and Excessive Sweating in young women

I am a 24 yr old woman who has been suffering from hot flushes and generalized hyperhidrosis since age 19. I sweat badly all over my body if I am slightly hot, feel any stress or strong emotion, etc. I've been getting these hot flashes about once a week, the level of intensity varying. I have seen a few gynecologists who don't really know what to do. I have seen one endocrinologist who simply gave me a pep talk and did not run any diagnostic tests.

I am currently taking Blisovi Fe as an oral contraceptive and that is my only medication currently. My hormone levels are low but this is normal for a woman taking oral contraception. I have regular periods.

My family doctor does not have much expertise in this area, so I need a specialist's opinion. Please note there does not appear to be any thyroid related problem or any kind of vitamin/mineral deficiency. My doctors have ruled out many potential causes for the hyperhidrosis.

Please offer any suggestions or recommendations for treatment.

Thank you.
