Finding solutions to inhomogenous 2nd order problem with function co-efficients

I have an equation of the form C(r) where C is a function of r and D and a are constants such that

C'' + (2/r)C' - D(f(r) + a)


I'm having problem solving this as f(r) is dependent on C in the following manner;

f = v(C)/ (C + k)

where v and C and constants. Does such a function have an analytical solution and what techniques / methods can I use to solve find C ?

Thanks in advance
