Put heatpacks on it for 15-20 mins twice a day for around a week. This allows the waxy substance within the cyst to 'melt' and be absorbed into your body. If this doesn't work, seek medical advice again.

I can't think of any distinctive link between the smoking and the re-appearance of the cyst. However, mentioning this to a doctor may not be the worst thing. You may have found another use for teh GanJa :thumbsup:
