I've been on savella for 3 monnths and thought it was helping but here lately I'm just down physically and cant do what I was doing before.Im only 29 and I tell myself this has to be something else but Im getting to where I feel like I have no immunity at all,feel tired and just worn out all the time,and my back pain has been twice as bad.It did help my muscles but what gives?Could ther be something else wrong?
