6 Months is a long time and concern is imminent at this level in time as to its cause(s). You did not say which anti-fungal/inflammatory cream was prescribed which gives you some relief! each different cream brand has different ingredients, and if we knew the brand we would know its content.
But! 6 months swollen, tells me its more than an infection, there is a possibility you have a small obstruction.
PH imbalances can cause pain , stinging and swelling.. look at what you have been eating and drinking since this started. Have you had anything new or in excess?
