Hi, I've Had Three Stents And A Drug Eluding Balloon

Hi, I've had three stents and a drug eluding balloon inserted on my left coranary arteries. Its been a week since the angioplasty was performed, I'm also due to have another angioplasty performed on the 29th of Jun and will have two further stents insterted on my right coranary. After I was discharged I felt fine the first night. Then the following day I experienced a lot of pressure around my neck, head and stiffness around my jaws. I also felt dizzy and nauseous, went to the hospital A&E they performed blood tests X-rays and ECG. All the tests performed were normal, I've been experiencing a lot of atery spasms around the top part of my chest neck and shoulders. The sensation I felt was as if the catheter was being inserted in the same area. I've been using Glyceryl Trinitrate and that seems to have eased the spasms. I'm now starting to experience pins and needles in my hands and feet also still feel a bit dizzy and a pit of pressure around my throat. Are all these symptoms normal and would they disappear with time?
