Hi Sorry this is a long one but I'm hoping that someone can put my mind at rest - basically I will make it absolutely clear that I do not think e-cigarettes are to blame for my problems -but am wondering if they could make any problem I have worse...or cause any of the symptoms (like the burping?) I am desperate to find out what caused this...(like I have also spoken to my dentist - I had minor dental work carried out earlier on the day this started -) I've been using e-cigarettes and normal cigarettes for about 3 months. Have managed to get my normal cigarette use down by half (8) and was planning on reducing further. I use standard (PG I assume) coffeee flavoured liquid. I started on 36 mg liquid and then got 18mg stuff but found it wasn't really strong enough - so was mixing it with some new 36mg stuff - about 2 days before this started...(which I know is probably a coincidence!) My health is a bit dodgy... I was diagnosed with a rare autoimmune blood clotting disorder approx 20 yrs ago after several clots (I was high risk anyway - long haul flights etc) but now I test negative for the disorder - and have had no problems since but so little is know about the disorder I have to err on the safe side (I shouldn't smoke full stop ..) About 3 weeks ago I had a pain in my left hand side under my ribs and into my shoulder ...it was catching when I tried to breathe - with my history I was taken to hosiptal, I coughed up small amounts of blood (nothing like the amount when I had a real PE) but the pain was so severe I ended up on morphine... They couldn't see a clot on VQ scan and an ultrasound/blood test showed up nothing gastro- intestinal and they also did some metabolic blood tests -normal I had terrible 'burps' in the days before and a big meal (family occasion I couldn't get out of!) the night before this happened ...I also have been taking aspirin daily for 15yrs + - so I am now on proton pump inhibitor medicine, gaviscon (which didn't seem to work on its own before the pain got bad) and have just started taking a replacement medication instead of aspirin which is easier on the stomach.. The pain has got better now -just get an odd twinge - and still getting a bit breathless (it does still hurt a bit on deep breathing (like when smoking!) also I've had a nasty cold that has gone onto my chest a bit ...avoiding antibiotics because don't want to throw something else into the mix The doctors have no explanation to what caused the pain - (3-4 in the hospital and 2 GPs) I have been told that it may have been a micro clot (didn't show up on the VQ scan) or maybe something to do with the aspirin or they roughly checked out my pancreas some of my symptoms did seem like pancreatis -and also I have a strong family history of gall stones -but this was the wrong side! Or may it was a combination of things... They let me out of hosiptal with a nicotine patch - but I started smoking again -so have stopped the patches - I haven't used my e-cigarettes since...just because so little is known about them I thought they were something I should take out of the equation... but I would like to get back onto them... So has anyone experience any of the symptoms I have - could it be the e-ciggie that was giving me the burps? Is anyone else a long term aspirin user and suffers no problems? Coughing up blood as a side effect of reducing 'normal' cigarette use? Or as a reaction to PG? If you were me would you start using them again ? Really any help/advice/feedback would be appreciated - I really am pro e-ciggie - I think they are fantastic -and that governments don't like them for taking their tax revenue and big pharma for taking us away from their patches/gum etc (BTW I was given loads of patches (2 weeks + supply) to bring home with me...I didn't ask for them - all paid for by the NHS - whilst my 'essential' medicines I got 1-2 weeks supply - hmmmmm)
