I am pretty sure I have been having panic attacks and anxiety for the past few months. It all started one night when I sniffed a small amount of heroin...I also had two or three beers that night...Being overweight and inactive I had a habit of feeling my heart whenever I drank or did any sort of drugs..to make sure it was working properly I guess..So that evening when I felt my heart, It felt very low..I'm not sure if it actually was that low or if i just wasn't feeling it right, either way, I thought I was dying...I immediately panicked, left my friends house and headed for home..during the car ride home I felt as though I couldn't breathe...however I felt my corotid artery and my pulse was very high...my left arm also felt like it was tingling and going numb...I thought for sure I was dying or having a heart attack..it really scared the caca out of me to the point where I almost had my brother drive me to the ER...a few hours later my mother who is an LPN insisted that I was okay and I adventually felt better...however I haven't felt the same since than...Whenever I drink, I don't feel the same..I think drinking almost makes me nervous, like I'm going to die somehow, and I wake up with terrible anxiety....I also get chest pain, particularly in my left breast plate..pains in my fingers and my feet go numb sometimes...I also sometimes feel as though I can't breathe..Also yesterday at work I had this horrible sensation in my chest..I felt like my heart was..doing something, I can't explain it well but it was very uncomfortable and scared me...i also felt sharp pains in my hands and feet..I'm pretty sure this sent me into the horrible panic attack that followed...I also feel my pulse in the morning and it feels very weak and fast..I feel as if my heart isn't functioning properly...I remember waking up one night, going to the bathroom and i felt my neck and my pulse was very slow and weak and than it literally went BOOM BOOM BOOM BOOM like ten times in my neck...I am a 21 year old male..5'11 295..large frame...Now my mother is an LPN and thinks that this is all anxiety and panic attacks and that I scared the caca out of myself that night...I went to two doctors..they listened to my heart, took my BP and some other stuff and said the same..one doctor actually said i can pretty much guarantee nothing it wrong with your heart...my uncle is also a cardiac nurse and listened to my heart and said I was okay...however I really can't shake the feeling that something is wrong...I have these heart palpitations and these horrible sensations in my chest (the sensations have only happened about 4 or 5 times)...My question is this...Could their be something wrong with my heart that noone is picking up on? I mean the doctors really didn't run any tests...Could they be just trying to dismiss this as anxiety to quickly...I really have abused my body for the past couple of years..mostly with food and smoking marijuana/cigarettes..I also used some other drugs sparingly..This is literally driving me crazy and I need some input..anything would be greatly appreciated..What should I do? Should I have some tests done?
