My advice to you is if you are having heart palpitations,feel lethargic,dizziness,chest pains and BP that does not stay down is to go to the ER.This is what would make me most comfortable.You are likely to continue to worry yourself sick(er) by staying at home.If it is a side effect of the medication then your Rheumy needs to review it as it might rule it out as an option.
I too would be angry over not getting a return call.If this has been a good dr then dont rule her out yet.Her staff could have got busy and she herself may not have ANY idea what you are going thru or the situation you are in.If she has hospital privileges at that ER request they call her if you hear"Contact your rheumy".Let the ER Dr and staff know you have been TRYING.You called the GP,they told you to call the rheumy,you did but they never called back.
Try to be calm.Tell them if it were just the BP that were up then you would make an appt monday and go in to discuss this.But all the other symptoms do have you worried.You should not be having to Lie on the couch afraid you are about to stroke.Thats unreasonable on their part and I am honestly surprised that the GP nurse just told you to lie back down and rest.If you are/were having a cardiac incident immediate treatment is vital.I am not trying to add to your worry just stating common sense.
So to me if you still feel this way then go to the ER.They can run tests and I would have them contact my rheumy.Like I said chances are she hasnt heard anything about this at all.But it sounds like you are unwell,in a high anxiety state over unanswered questions and this would be one way to solve them.If you dont feel like you can work be sure to ask the ER dr to write a note keeping you from it until you can follow up with a rheumy visit.Call first thing on monday and get in there.If they cant see you then go to the GP.They can handle BP issues..they may not want to because of the SLE and cellcept but they can.
Just take a few deep breaths,try and calm down and decide if you want to wait until Monday or if you really feel like you need to be seen if for nothing else than peace of mind.You shouldnt have to spend the weekend on the couch because you are concerned for your heart.
Be well and keep us updated.
