I got a tattoo done that runs the entire lower part of my left arm yesterday, I was advised to take off the clean film and wash it with soap and then re-apply new clean film and keep it covered for 24hours, I went to work night shift and there was a load of sweat that built up in the clean film so I kept washing it with soap and more clean liquid kept coming out, when I got home I went to sleep and when I woke up there was a thick slimy liquid on the tattoo which I attempted to wash off while having a shower, I was also advised to use bepanthen nappy rash cream which I started using today, however during the day this clear liquid had turned into like a line green liquid which built up during the day which I washed off using warm soapy water with a flannel and let it air dry so not to agitate the tattoo any longer than I have to, having placed my hand over my tattoo where the thick green liquid was it's quite hot, is this usual or is it a sign of infection?
