 [ Symptoms ] what could be causing upper backspine pain why do i have bruises  i am 18 yrs old and for a week i have been having upper backspine pain it hurts to be laying on my back or even sitting on the couch and leaning against cushions i can not prop myself up against pillows because that will hurt my back i only feel better by laying on my sides or sitting while leaning forward i noticed today that i have 2 bruises near the area that is hurting i do not know why because i never did anything that would have caused this painbruising any ideas what this could be thanks [ Disease ] hi your find that this is the big problem of losing weight if have really put on the pounds and if its be a long period then yes you will get lose skin but before you go off and get it trimmed back first make sure your at the weight you want to be this procedure is not cheap and when that lose skin goes you will lose the odd couple of pounds more do hope this helps you good luck
