You'll find everyone's experience is different - there are hernias and hernias and hernias - all sorts that pop up in all sorts of places in various stages of hernia-iness. What your recovery time will be like will depend a lot on the surgeons you have locally and the procedures they use, each will have their own approach depending on where and when they trained.
There is also the unexpected - my hernia - a periumbilical ( don't think I'm dynamic enough to get a sport-induced one) is commonly treated with keyhole surgery - its referred to a perambulatory surgery in the sense that you walk into the hospital in the morning and walk back out after surgery in the afternoon (looking a bit monged)
But - I had to sign two consent forms one for the keyhole and one for old school hatchet work - thats because as much as they'd prefer the keyhole approach the surgeon can't be sure its a suitable or safe procedure til they get inside - weirdness in your anatomy, adhesions (your puddings being stuck to the wall of your abdomen) and damage to your puddings as they work - any of these things mean bigger surgery and a much longer recovery - you won't be leaving the hospital for days and will be a long time recovering. With the keyhole type surgery the repair is pretty much full strength from the word go - it only discomfort that limits you. With more conventional surgery it takes time for the repair to be strong so your activities are much more heavily curtailed - I've even seen advice not to raise your voice whilst in recovery.
For me I shuffled out of the hospital just after lunchtime. It took me a long time to get over the effects of the anaesthetic - sick and bewildered for 5 days or so, and could get quite fatigued quickly for a week after that too. One my feet but moving pretty gingerly for a couple of weeks - getting more mobile in until pretty much brand new at 4-5 weeks, for about as long again I could feel little pin pricks where the repair is when doing anything strenuous.
At the time there was a guaranteed maximum waiting time of 12 weeks - with the option to get in sooner on a cancelation. Knowing this I was able to put myself on the list 3 months before christmas - I'm self employed and xmas is dead month for me so it limited my losses.
However - That was just before someone had the bright idea of not quite voting in a tory government - what the waiting times are like just now I don't know, my mums been waiting 6 months just to get a date for an operation
