Just Curious If This Is Anything To Be Concerned With

just curious if this is anything to be concerned with ... I have scoliosis and ms ... so i'm familiar with pain and so forth and what goes on with my body ... however, over the past few months I've had this unbearable pain on my lower left side ... sometimes it feels like there is a baseball inside that i just want to pull out of there ... and when that starts bothering me I've noticed my bowels change to sometimes have dark red blood or mucus like stuff in them and i get really strange bruises on my inner thighs ...
