I used patches initially and ended up with a reaction like you've got, turns out I had an allergy to the 'glue' that's on plasters and patches. I'm now on gel it's much better. Contact your GP as soon as you can
Thank you so much for advice! 😊
I get them a day before I’m due to change my patch
Could be a bit of a reaction to the patches. Give it a few more days and if still no better, go back to GP?
