Renal Colic

I've had renal colic as a result of kidney stones getting stuck in my left ureter obstructing the flow of urine. This is an extremely painful condition which has really knocked me sideways and has meant I have not been able to sit up straight let alone concentrate on drawing anything specific. I decided to make a drawing of the experience using some new inktense block I had bought.

I closed my eyes and imagined the edges and the shape of the sensation. I then imagined the colours it might be and sketched it.
