Blood pressure drop symptoms and conditions

Took 1 dose. Within hours, I awoke with a very dry mouth and severe heartburn. Went to the kitchen for water and nearly passed out. Nausea, so I made it to the bathroom. Cold sweats, then chills. Felt like I had the flu. Every time I stood up, I nearly passed out and kept having same symptoms most of the night. Next day, at work, I had to be taken to the nurse, who figured out that my already low blood pressure was dropping dramatically when I stood up (as well as my pulse rate increasing). I threw up all over the doctor's bathroom. Still feel awful 3 days later. Dr. pretty much indicated that blood pressure drop couldn't have been from the Crestor, although my father has had same thing happen with EVERY statin they've put him on. Now, my leg aches and my urine is dark

I am a female on Flomax (to try and speed the release of a kidney stone). I've been on the medication for 4 weeks and my arms (including my hands) and legs have become very weak and tired feeling all the time. I feel dizzy most of the time, due to Flomax causing a blood pressure drop, which also leaves me freezing (even in 90-95 degree weather). I now have begun to feel nauseated and can't stand the thoughts of any food whatsoever. There has got to be another medicine that can do the same thing as Flomax without all the side effects.
