Sounds like haemorrhoids. Use Ansuol ointment or suppositories but see your GP if:
- You've had them repeatedly before
- Bleeding around your anus or in the stools occurs
- You've had them longer than 2 weeks
- They're persistent or severe
Also if you're taking steroids avoid Anusol HC (it has Hydrocortisone which is a corticosteroid used to damped the inflammation but in too high doses is very problematic), so just get the regular Anusol.
Ultimately I don't know for sure and whether you go to your GP for more advice or pharmacist to purchase an over-the-counter product, talk to them about your symptoms.
