It will vary, some people do not experience trapped wind pain or have pain from the port at all, some people have slight pains and some people have more painful effects and suffer from a lot of trapped wind.
If you're unsure about any pain and the painkillers given to you aren't helping, your first port of call will be your provider. Otherwise to help with wind pain try moving your arms in a gentle windmill motion, walking and moving around. I found boots own equivalent of deflatine helped, but so can peppermint tea or cordial.
Don't go 6 hours between your pain relief, for the first few days take it every four hours, that way, it doesnt allow the pain to really set in and the paracetemol will be enough if you take it regularly.
