Thank you for posting this question ukwildcat, After a very bad day this week, could only lie flat and had bad chest pain, leg pain and dizziness all day, i was feeling too weak to get up to get BP monitor, couldnt move and didint know whether it would have been worth my while to go to A & E or not. My POTS doctor also told me all i could do was wait it out the last time i asked her should i go to the hospital too, but you get to the point and think why the **** should i have to wait it out!! im looking forward to seeing the responses to this one!!! thanks again for posting
