I am not quite sure of your parameters. As far as I can make out your equation is [itex]h''+\frac{1}{r}h'=0 [/itex]. Now I wonder: Is r a constant? If so, just integrate and get [itex] h'+\frac{1}{r}h=C[/itex] (C is a constant) and from there [itex]h(x) = C_{2}+C\cdot x + C_{1}e^{\frac{-x}{r}} [/itex]. Nom determine the constants to fit your constraints.
