I've been naughty and forgot to use my preventer for the past few days (had to hide it and so out of sight out of mind!). I remembered tonight and used it and now I feel worse than I have all day. My chest is tight and I feel like I can't quite breathe deep enough. Is this normal? I did over do it a bit at the gym earlier but haven't suffered too badly for it this afternoon. My pf is about 420, which ie about right.
Is this me being weird or can this happen?
