Some medical history:
I am 23 years old. I was very sick for about December till May. I had hypertension (sometimes severe at 200/160), palpitations (episodes lasting anywhere from hours to weeks), chest pressure, chest pain, and exercise intolerance. I've had tons of tests done and thousands in medical bills without any significant findings. I wasn't anxious when this all started, but I was so ill some days that I couldn't get out of bed. My doctors think it could be anything from anxiety to an infection (Such as valley fever). I really think it was something like an infection, as I don't believe anxiety would make me so physically sick and disabled for 5 months straight. It was sickest I have ever been in my life, and it was very traumatizing.
Gradually over the last couple months my blood pressure, heart rate, chest pressure, and chest pain returned to normal. However, I think I have developed a fear of my symptoms coming back. In other words, I don't think panic attacks were the root of my problems, but I think they have developed since my illness was very traumatic. I honestly thought I was dying when I was at my worst, and I felt so ill at some points, I went from scared to being ready to accept death (I wasn't suicidal or anything, but I think this was just a biological/chemical reaction to my pain). Anxiety medication, beta blockers, etc couldn't get my heart rate or blood pressure under control when I was at my worst. Ativan did help me calm down, but it didn't change my blood pressure or heart rate much when i was sick. I avoided alcohol, caffeine, dark chocolate, and marijuana. All of these were triggers.
I think I have recovered from my illness (not 100%, but pretty close now), but I sometimes have a fear of becoming ill again (is there a phobia for this?).
I've been very stable for a couple months now, but I had a bad attack after smoking some Marijuana today. I had a friend take my pulse, and he said my heart rate was about 200 before I left to the hospital. I don't smoke habitually, just socially. I went to the hospital, and by the time I got there (30 minute drive) my heart rate was lower and stayed consistently between 130 bpm to 140 bpm for a couple hours. They gave me beta blockers and ativan, and released me once my heart rate was around 100 bpm. My normal resting heart rate is between 60 and 80. I asked the doctor if he thought it was just a panic attack triggered by the marijuana, and he responded that he couldn't tell me for sure. I never had a reaction like that before, but I don't think I will be using it anymore.
So, does this sound like a panic attack? I hope that is all this was.
