Things you can try yourself to reduce a painful erection

There are things you can try to reduce your erection.

Do

  • try to go for a pee

  • have a warm bath or shower

  • drink lots of water

  • go for a gentle walk

  • try exercises, such as squats or running on the spot

  • take painkillers like paracetamol if you need to

Don't

  • do not apply ice packs or cold water to your penis – this can make things worse, particularly if you have sickle cell disease

  • do not have sex or masturbate – it will not make your erection go away

  • do not drink alcohol

  • do not smoke

Call 999 or go to A&E if:

  • you have an erection that lasts more than 3 to 4 hours
  • you have sickle cell disease and a painful erection that lasts for more than 1 hour

An erection that lasts this long needs to be treated in hospital as soon as possible to avoid permanent damage to the penis.
