Can I pop my own ganglion?.......?

the ganglion on my wrist is driving me mad, its so painful. I don't have my hospital appointment until 8th Sept and people can telling me I could easily do it myself by just boiling a pin to sterilise it and then pierce the top of the ganglion to drain it, then apply tcp and put a plaster over. Do you think this would work? I know all the hospital do is a very similar thing really.
