Have been twitching for nearly 29 months and have had 'breathing issues' for 14 months. Breathing issues manifest with inability to take full breath, bloating, fatigue after exercising, particularly when walking uphill, sweating etc.Is it generally considered, at 14 months, to be too long for something nasty, e.g. respiratory onset? I think it's hyperventilation, definitely, but I'm getting stomach/chest muscle twitching which is freaking me out.Any comments or observations welcome.
