In suffering from drastic weight loss fatigue back pain n my knees they feel like they're not even there. I'm 27 and I also have bleeding when passing motion and urine is always dal yellow. Feel so uneasy and restless every time. Have trouble sleeping as well not even fr a single day I'm able to have peaceful sleep. The drastic weight loss from 94 to 55 in just over a month is worrying me even though I eat a lot.
