[|Human|] I had a staph infection 6 months ago on my thigh. It scarred. Tonight the scar feels warm swollen and is tender. I can t tell if its red due to a tattooin the same location. The tattoo is 7 years old and not a factor in either case just mention it because it makes it hard to see color changes. Is that normal? When should I start to be concerned?
[|AI|]  HI, thanks for using Chat Doctor Since the tattoo is 7 years old it is unlikely to be contributing to your current symptoms. Infections can present with increased warmth, redness, tenderness, swelling and discharge. Warmth, redness, tenderness and swelling can also occur if an area is inflamed even if no infection is present. You can consider using an anti-inflammatory Chat Doctor.  Monitor the area for 24 to 36 hours (unless notice a discharge or symptoms worsen prior to this), if no improvement occurs with medication, then you should visit your doctor for assessment. I hope this helps
