I have lots of pink lumps all over my legs. They feel like bruises but look like insect bites . They appeared around this time last year as well and my doctor had no idea what they were. It makes sitting, walking and lying down really uncomfortable. They range from half way down my calf to the very top of my thighs, with the largest concentration on the outside of my left thigh. Last year we guessed it might have been from wearing tight trousers, but this year I haven t worn any for months, and that wouldn t affect the inside of my calf. I ve no idea what it is.
