[|Human|] 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 doesnt 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?
[|AI|]  Hello! Welcome on Chat Doctor ! Your symptoms do not seem to be related to MS. Repeated trauma or a bad mattress could be the reason of such skin lesions. Anyway, if these skin lesions do not disappear after changing your mattress, I would recommend consulting with a dermatologist for a physical exam and some blood lab tests: - complete blood count for anemia-iron levels-blood electrolytes- coagulation tests. Hope you will find this answer helpful! Best wishes,
