A few weeks ago I reported many of the side effects so many of you have reported on. After several blood tests with my endocronologist, results came back normal. I have now been off Singulair for about five weeks and have noted only one improvement thus far: less headaches (especially after drinking alcohol--that being defined as one or two beers/glasses of wine. I think this has to do with less constriction of blood vessels in the brain). I'm returning to my cardiologist next week. I'm thinking I may have what is called Postural Orthostatic Tachycardia Syndrome which can be described as a periodic low blood pressure disease that causes dizziness, faintness, ect. Many other symptoms of this disease have been mentioned on this site (including Shy-Drager Syndrome which is most scary). Doctors don't really know what brings on Pots but one suspicion is viral/bacterial or drug induced...jury is completely out on this, however). Most notable is a sudden change in bp after stooping and standing up--bp drops, palpitations begin, extreme fatigue generally follows. A table tilt test should help with the diagnosis. Question: Are any of you familiar with Pots and/or have any of you experienced similar symptoms? Thanks. Fortuna
