Mono is hellish. Somehow I can't see Soderling returning to the game any time soon, at least not from recent updates on his condition. I hope he can just focus on getting himself well and let the tennis go, but maybe becoming a father might do just that by helping to let him see things in perspective.
It occurs to me that all the top 4 have, or have had, health issues. Nole now seems to be managing his gluten intolerance; Nadal was born with some abnormality in one of his feet for which he has to wear specially made tennis shoes and have regular pain-killing injections; Federer had an unspecified back problem for years; and Andy has to contend with his bipartite patella which can give him pain, especially sliding around on clay. Very strange.
I feel tremendously sorry for Soderling. Even if he comes back, he's clearly not going to be in the same shape as before.
Back in 2008, I remember a lot of fans out there, especially Federer fans seemed really skeptical about Nole's condition, that he had trouble with the heat, but I think that had a lot to do with the fact that, Nole had beaten Federer in the semi that very year, so it was probably more based on bitter emotion/feelings than anything else. I had to defend Nole quite a few times saying that his conditions were quite legitimate. But at the same time, it's quite ironic when you think about that Nole, in fact, has won the 2 AO Slams since then and AO is notorious for heat and exhaustions to the point that they had to come up with the roof because of it.
As to Federer's mono, I'd say that's even stranger than anything we typically see. The guy I like is an ardent Federer fan and that's an understatement, but he's a doctor as well and he says that it's quite possible to have a mild case of mono, which he thinks Federer had in 2008. I took his word for it but at the same time, you have to keep in mind that he's a crazy fan of Federer who also happens to hate Nadal with a passion. Mono seems like a serious disease and I am not sure if it’s possible to have a mild form of it.
