Suggest Treatment For PET With Low Blood Pressure During Pregnancy

Hi, I m 32 years old, I m 5ft7 and weigh about 128lbs, although I m about 138 now since I m little over 6 months pregnant. This is my second pregnancy (first one was in 2008 and had no complications). Since my first trimester I ve been suffering from PET (patulous eustachian tube). In the beginning I was still able to control my condition because I knew what could trigger it (like fatigue, certain activities, etc), but unfortunately for the past 3 weeks it s changed for the worse and I ve been having PET constantly throughout the day with now relief, unless I lay completely flat on my bed, which I can t always do having a 2-yr old boy jumping around me all day. With my first pregancy I only started having PET around my 8th month and it wasn t constantly, I could easily control it so it didn t control my life like it does this time around. Although I ve read a lot about PET and I know that the tissue around the ET can soften during pregnancy causing it to open up, I was still wondering if low blood pressure could have anything to do with it, too. I ve always had low bp and now that I m pregnant I lack a lot of energy and I m always out of breath. My bp is about 100/50. I know that before, being tired was one of the triggers for my ET to open up. Anyway, even though I can rest assured that this annoying problem will go away in 3 months after I give birth, I still would love to get some relief now, because it s driving me crazy. Is there anything I can do to get my bp to go up? Not only to see if my PET would go away, but also to get more energy. Thank you for your time.
