For the last 3 months, I have gained 40 pounds, my muscles all over my body feel weak and like jello. I have a hard time going to the restroom, I do have a lot of pain in my right kidney. Also since Ive had this massive weight gain, when I wake up, whatever part of my body that is laying on my bed is on fire. I have got to where I am either sleeping nonstop or I cant sleep for hours. I have no motivation to do anything and for me that is very unusual.
