I've been a frequent smoker for the last 2 years. I have a fear of doctors and needles and anything white coat. Recently I had eaten a nice big chunk of brownie that from what doctors say dropped my Blood pressure to the point where I lost consiousnes and went into a seizure that landed me in the hospital. From the hospital I had to get cardiac tests on my heart because heart disease runs in my family and there was a fear it could be related to me pass out. Since then I haven't passed out or had any repeat situations. Except now occasionally when I smoke I get a rapid heart beat some pain in my chest that shoots into my left arm and neck, jaw and I get really really pale. Im sure it's just my anxiety but I was wondering if anyone had has a similar situation or any tips to deal with it. I occasionally get the same feelings sober as well.
