I didn't have surgery whatsoever, but I do know someone (my ex bf) who had mono when he was 14, and he has had his tonsils taken out too, it did help him although his recovery from mono was a slow process.
I can't say much about it, the fact that I can't back it up with medical knowledge and/or experience.
I can ask him though, on what his take with regard to your issue.
