I've recently been in Hospital first time for 5 nights for a severe skin condition and then last week a skin rash on my arms and legs also neck pain, headaches and a water infection. When I was in Hospital my tops of legs were hurting so much and burning and swollen, I just assumed chub rub, as I am overweight and have put a lot of weight on recently. I did end up asking my consultant who said inflammation. Maybe she was just being polite instead of saying chub rub. They hurt so so much. I'll try to attach some pictures and I think it shows some of the rash too. I had a look on Google and there can be reasons like Lipedema and other things but I'm just fat and have chub rub I assume. Any ideas - even if yes your fat you've got chub rub. My goodness they Hurt so much and just the area feels so painful and like it has fluid. Thankyou replies appreciated.
