Hey everyone.
I am kind of new here. I have not been diagnosed with anything, but had a reaction to something a month back. I have quite a few disabling painful conditions, one being a bladder condition called Interstitial Cystitis. I have tried all treatments they offer for it to no avail. My doctor recommended I try medical cannabis as they offer it here where I live in Illinois. I went to the dispensary and the man talked me into buying this thing called a cannabis oil vape pen. He said it was very safe( he said way safer and healthier on the lungs than smoking is). I was against smoking because I watched my mom die of lung cancer that was caused by smoking cigarettes for years. He assured me this was safe and benign. Anyhow, he explained to me how to use the device as I had no idea how to use a vape pen. Long story short, I went home that night and decided to try it. I did exactly as he said, but immediately after I breathed in I started coughing like crazy! Also it felt like someone poured hot acid down my throat and into my chest! It was so awful and so scary. I called the medical dispensary back after the coughing calmed down and I could talk again. I explained to the manager what happened. He immediately apologized saying the man who told me how to use it should have told me to ONLY take a small puff of it! Well, the customer service guy who explained to me how to use it told me to take a nice breath in and hold it for a second. He should have told me to take a small puff only from what the manager said. Anyhow, he said it should pass in a few hours. Well I did not start feeling better for a couple days. This happened on a Sunday and I did not start feeling better until Tuesday. Then on Thursday I felt bad again. I ended up going to the Emergency room. The ER doctor listened to my chest and said it sounded clear. He also did a chest x-ray and it was normal. He said he believed what I had was Aspiration Pneumonitis. He said basically the stuff sent a mist into my chest when I breathed in and it irritated the hell out of everything. He said it should get better in a week or so. After 5 days I did start feeling better and for about two and half maybe three weeks I felt back to normal. Then on this past Wednesday I had a tickle in my throat that made me cough a little and within a couple hours I felt icky again, like just irritated in my upper chest and having this itchy feeling in my throat( it it that hive itch as I like to call it that makes you want to cough all the time). My hubby and I ended up going back to the ER again on this past Friday. The ER doc I saw this time listened to my lungs and chest and said everything sounded very good. He said he wanted to re-do the chest x-ray just to be sure no infection set in though he did not think so since I sounded clear. The chest X-ray came back clear. He said he felt maybe there was some superficial irritation still going on and that might be what is causing me to have this itchy feeling in my throat and making me feel like I always have to cough. When I do cough, it is not a hacking cough, it is more of a single cough to clear my throat and there is no mucus coming up. Though I do feel some mucus down in my throat that is probably dripping from above( maybe a slight post nasal drip?? Not sure though. I have NEVER had any kind of coughing or respiratory issues before using that stupid Cannabis vape oil pen. I am worried that maybe something happened or got damaged. I asked the ER doc if it could be a infection in the upper airway like the windpipe and that a Chest x-ray would not see that. He said usually there is other symptoms with an infection like Fever and that I would be coughing up stuff and he would likely hear cackles or something when listening to my chest. He said there could be superficial irritation though. I don't get why I would go back to normal and then three weeks later I just get a tickle in my throat that makes me cough and now I am crappy again. I got that tickle in my throat Wednesday Night and felt bad so went to the ER this past Friday and it is now Sunday and I still have that constant itchy feeling in my throat that makes me feel like I always have to cough. What could this be?? How can I have this feeling but yet when the doctor listened he said it all sounded clear and the x-ray was normal? I am worried using that cannabis oil vape pen could have damaged something. Also due to having the single coughs to clear my throat so often because of that itchy feeling, my throat is irritated because of that I am sure so I feel kind of this burny irritated feeling in there as well. I am drinking lots of water to keep things moist in there. I just cannot tell if this itchy feeling is coming from my throat or my windpipe. I mean if an infection with bacteria/fungus had set in my windpipe how would I know it? The ER doc claims there would likely be other symptoms like Fever and stuff coming up and he would hear it when listening. Does anyone know what this could be? I mean if I could describe the feeling, it feels like it literally itches in there. Not scratchy like when you catching a cold, I mean itchy like a mosquito bite and it gives than constant sensation that I need to cough. There is No wheezing or anything from what the doctor said though. I am miserable and worried that something bad has happened from using that Cannabis oil vape pen! I only used it once and I cannot believe it has caused me all this grief! Praying it did not cause permanent damage somehow.
