Description of intervention(s) / exposure
The interventions consist of 3 different ointments:

-lignocaine 2% and diltiazem 2% in polyethylene glycol (PEG) base

A 2cm length of ointment will be digitally applied to the anal area 3 times per day for 5 days from the procedure. Each participant will record in a written diary that the ointment has been applied.

Brief summary
Haemorrhoidal symptoms are among the commonest complaints of mankind, it can occur in up to 80% of the population, involving any age and affecting both males and females equally. Surgical haemorrhoidectomy is most commonly used for 3rd or 4th degree haemorrhoids. However, surgery is associated with severe postoperative pain that is a source of such anxiety that some patients decide not to undergo the operation. Due to this, another non-surgical method can be used such as rubber band ligation, however this still requires pain relief. Research has suggested that current forms of pain relief are short term, caused more pain. Therefore, topical local anaesthetic agents are the next appealing option although have not been as successful as anticipated. Lignocaine in combination with Diltiazem are options that have not been used in this area and could potentially be more effective in relieving pain.
This trial will examine the role of diltiazem and lignocaine in reducing post-procedure pain.
