In general, lack of healthy lifestyle may lead to erectile dysfunction at the early ages.

Mainly in terms of daily physical activity, proper proteinaceous diet with fruits and vegetables are advised for good sexual functioning.

Medications are not advisable for long term treatment.
It can be given only for short term and temporary response.

Swelling could be related to any structural problem,...you may need to consult general surgeon.

Hope this information would help you.
Thank you.
