Why did a lump appear more than a month after taking progesterone in early pregnancy?

Patient's question:

No

Doctor's answer:

Hello! Progesterone is an oily preparation, and its absorption through the skin is slow, making it easy to form hard lumps locally. This may be the reason for what you're experiencing. Wishing you good health.
Advice: It is recommended to apply warm compresses to the lump, massage it frequently, and use magnesium sulfate powder dissolved in water for wet compresses. Gradually, it should subside.
