Thanks for your query.
Based on your query, my opinion is
1. Lumps/ swelling in thigh is less than 1 cm and decreasing in size. These are probably enlarged lymph
nodes secondary to infection in the labia.
2. Since the lump size is reducing, not to worry, it will come down with the treatment for primary lesion which is on the labia.
3. Labial lesion could be a bartholin cyst
which is infected, or just folliculitis
. If the lesion is painful, take analgesics and a course of antibiotics, it will settle. You may apply antibiotics over the lesion if it starts discharging.
4. If the lumps over thigh do not decrease/ there is a further increase in size, get a fine needle aspiration cytology done to rule out lipoma/ soft tissue
lesions as they are known to occur there.
Hope this helps.
