I have normal prolactin levels, yet have lactated for 15 years and no one seems to be able to figure it out. I have no pituitary tumor. It has been checked twice. TSH level a little low, but not low enough to be on meds. Periods have been normal up to a year a go they are now 40 days apart instead of 28. I have had many miscarriages. Hormones are normal. I crave and drink Himalayan sea salt and water all day long. I get dizzy if I don't drink enough. I urinate a lot, wet the bed at times. I sweat a lot and have high anxiety levels. I am 31 years old with one child. Doctors have told me this far they don't know what is causing it and have offered me drugs to stop the lactation. The drug side effects are brutal and the lactation comes back almost instantly after stopping them. I thought brainstorming with a few doctors may have some idea what's going on. Thank you in advance.
