Tolkien gives his own interpretation in Letter #246:
'Alas! there are some wounds that cannot be wholly cured', said Gandalf (III 268) – not in Middle-earth. Frodo was sent or allowed to pass over Sea to heal him – if that could be done, before he died. He would have eventually to 'pass away': no mortal could, or can, abide for ever on earth, or within Time. So he went both to a purgatory and to a reward, for a while: a period of reflection and peace and a gaining of a truer understanding of his position in littleness and in greatness, spent still in Time amid the natural beauty of 'Arda Unmarred', the Earth unspoiled by evil.
----
I find interesting his inclusion, "if that could be done." It casts doubt on the ability of going to the West as a complete restorative for Frodo, at least in Tolkien's mind.
