Hello,
For your
dizziness, I would suspect that your low blood pressure is responsible for this. This could be related to your blood pressure medications, along with other causes such as
dehydration if you haven't been drinking much fluids lately. As for the
fever and pain, this could be a
lupus flare as you said. As for the bladder issues, it may be related to the
stress your body is dealing with from the other issues, or it may be unrelated, it is unclear at this point.
I would recommend that you call your doctor's office as soon as possible and hopefully they can see you within a few days. In the meantime I would not take any blood pressure medications until the blood pressure returns to normal, and if you have worsening or new symptoms, I would not hesitate to go to the ER to make sure nothing needs to be taken care of urgently.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Aaron Branch, General & Family Physician
