Yen,
So you do have the patch of numb feeling area too. hmm..then seems like this is a pretty common symptoms. Will check with my gyane tml why is this so.
I also have the Mini Electric pump, pass down from my SIL, dun wana spend $ to buy a new one, think will try to latch on if possible. Ive yet to buy the spare tubes n parts etc. Not sure where is these selling? Most shopping centre does not seem to carry the tubes etc.
