Hi Samuel, I have a soft tissue area where in my bum meets my thigh. This morning I woke up and a large area around it is very swollen, red, and hard. Can you tell me the cause of this? And what I should do? I live in a quadriplegic residential facility, I am a 34-year-old male, injury level - C4 complete, no one can give me an answer. Please help, Greg, Perth Western Australia
