Hi and Welcome
I was on them about 5 yrs ago I found I started on 5mg but quickly went up in dosage, I was only on them a short while as I came off oxycodone but I found they did work the only problem was I developed a bad Rash even switching spots didn't help I got another rash straight away so had to stop using them and went to Tramadol .
5mg is a low dose so I wouldn't be too worried about side effects , just when you use them put it on a different body part each time to help prevent any rashes.
