J.L.
I have heard adults have a way more difficult recovery from tonsillectomy than children. It has to do with the fact we have more blood vessels and that means longer healing and recovery and a higher risk for more inflammation and bleeding. From what I've been told by family and friends who had surgery as an adult, it sounds like you're getting off easy.
I would be concerned, however, about a secondary infection. As with any surgery these days, this is a real and serious concern that shouldn't be discounted. Are you still on antibiotics or pain killers or are you done with that? My young son had Codine (sp?) after his surgery, and I found out it also helps with phlegm and inflammation besides managing the pain. I was leary of the meds and wasn't giving it to him because he said he had no pain. He did however have alot of swelling and phlegm. The doc got on my case saying the med was really for the inflammation and to follow the prescription. So I did and my son recovered much quicker than without it. Just something to consider.
Also, what are you eating. Stick to soft foods until you're fully healed up. Stay away from dairy and spices as this causes phlegm and inflammation. The old thought of ice cream is wrong. The dairy nixes the benefits. Popsicles and cold drinks are a better way to go. Keeping the throat moist at all times is important too.
Take your temperature. Do you have a low to medium fever? This is an easy way to find out if an infection is at play.
I say stay on top of it. A good doctor will check everything and not discount your concerns. If he does, it won't hurt (no pun intended) to get a second opinion. Hope this helps.
Here is information on complications for adults - one article says swelling in the tongue is common but must be watched closely for infection.
