I have a large pinkish discoloration of skin around my mid spine and brown bruise marks along my back left ribs. My mid spine is very painful. I have ms and my neurologist doesn't seem to think that it is related - they have mentioned that I may have pressure points on my back. I only weigh 100 lbs. and was sleeping on a very bad mattress which I have replaced with a serta firm firecreek mattress on Thursday of last week. Could these marks or bruises and pinkish skin discoloration, in fact, be pressure point bruises, or should I seek medical attention to determine if something else may be going on?
