Hi,
Welcome To HCM & Thanks For Asking Your Query Here
Lumps on the penis can have several causes. Many penis lumps are harmless like penile papules ,
Fordyce spots and
Lymphocele and these don't need treatment and subsides over time
sometimes injuries to the penis can also cause small painful swelling on the penile shaft and head ,injuries to the penis can include scratches and Bites, knocks, burns. Sometimes contact with creams and lotions that cause a local
allergic reaction can cause painful swelling.
however as u r not circumcised and your partner had an UTI there is high possibility of other medical conditions including an infection and specially a
STD (
Sexually Transmitted Disease )
it needs thorough medical check up and investigations to spot a confirm diagnosis
you should Avoid sexual contact until you feel free of pain and bump
also do not apply any creams, lotions or homemade remedies to it , You can Take over the counter pain killer like
ibuprofen for relieving pain
finally i would strongly suggest you to see Your dr , he may go for all necessary medical investigations to rule out any underlying medical condition including an STD
I hope it help
Thanks & Get well Soon
