That sounds really serious.
We cannot emphasise enough that you see a doctor about it as soon as you can before it catches you out in a potentially dangerous situation.
There could be a few different reasons for this but there are no doctors on these forums and, even if there were, no one could offer a diagnosis of any sort of validity without a direct examination.
Please get yourself to a doctor ASAP.
Sorry I have no idea what might be the cause of it...
AlthoughI think in the meantime just have a chat to your Dad or anyone close to you to let them know that there may be something wrong. I think your parents will be just as concerned if not more so than what you are.
Great work. Get off to the doc as soon as you can. Lex is right - dissy spells can mean a bunch of very serious and not serious things - but you totally need to go see a GP to find out.
Does your dad know how serious it is? Make sure you get there ASAP and let us know how you go.
Seen something fantastic on the forums?
