Hi, I vaguely remember that runny nose or post nasal drip can be a sign of high prolactin levels?? I havent had my prolactin levels tested but its quite possible they are high as generally guys with high E2 like me also have high prolactin. Im treating the E2 with arimidex but unsure if this will have a carry over affect to prolactin. Had a theory or a light bulb moment where i thought maybe this is the cause of my sinusitis. the constant post nasal drip which eventually it gets blocked and then an infection occurrs?? I do improve on antibiotics but crash again once i stop. Maybe its the prolactin and or maybe sinus infection or both but im feeling like crap. post valcyte i was ok and i dont get any viral type symptoms like sore neck glands etc its just all sinus symptoms with facial pain, brain fog, cognitive stuff, post basal drip. and hypertension when im really clogged up with my bp the other day of 155/105 the dyastolic pressure is high and i think what causes alot of the facial pain and headaches, whats interesting is generally alot of sinus treatments like sudafed etc increase blood pressure but when i take it my bp normalises as it reduces the presssure in my sinuses. So i would like to know if anyone has documented high prolactin that gets post nasal drip and also how they have treated prolactin problem. i have heard that active b6 called p5p can help in doses of 300mg a day. theres also drugs like bromocriptine and dostinex. Bromo is easy to get and cheap. interested to hear from others, cheers!!!
