I just started taking mononessa (28) on sunday 8/12 and I started having rib/ back pain on wednesday and it seems to be getting worse. I thought it was a rib muscle but it is excatly where my kidney is and it is radiating, It gets better but when I lay down worse, and sometimes I lose my breath from the pain, I also have a hard time bending over for extended periods of time. Is this a side effect? will it go away?
