That would be a big mistake to injur oneself in such a way. It can lead to infection and even death.
No, and it could make it worse. Heat should not be applied to anything swollen. Swelling is usually helped by cold, not heat. But if it is your tonsils, you may need to find out if you need to have them removed.
Yes, obviously. Find out why - you could be contagious. Could be a goiter, could be mumps, or worse. My little brother discovered throat cancer when he had his tonsils out. How olds your brother? Can little kids get cancer?
It's the same.
Swollen legs are often due to weakness of the leg veins which have to circulate the blood against gravity. When they are weak, blood pools in the veins so that fluid leaks into the tissues. This causes swollen legs. Pregnancy causes swollen legs due to the weight of the baby on the pelvic veins. Kidney problems and heart problems can also cause swollen legs and ankles. If the problem is not due to pregnancy, and if your doctor confirms that your heart and kidneys are ok, then don't take diuretics as they can make the problem worse.
It will just make problems worse.
Walking is not usually good if you have swollen ankles. It is best to prop your legs up and let the swelling go down.
If there is existing problems yes it can and most likely will become worse!
That is hard to answer because you are comparing a disease, influenza (or "flu"), to a symptom, swollen glands. There are many diseases and disorders that can cause swollen glands. Swollen glands are mostly an indication that your immune system is reacting to an infection or inflammation of some kind. Furthermore, the outcome of the flu vs. that of swollen glands can vary quite a bit. Most of the time, flu is just a slightly more uncomfortable inconvenience than is a common cold (both flu and colds can cause swollen glands). On the other hand, approximately 36,000 people in the US die from the flu every year (elderly people are more vulnerable). So, flu can be worse than swollen glands in this scenario. Mumps is one of the diseases that can cause swollen glands, and although it is usually not that serious in children, it is often very dangerous for adults. Mononucleosis causes swollen glands, which is an even more serious disease if untreated. And toward the worst end of the scale, leukemia ("blood cancer") can cause swollen glands as a symptom. And approximately 22,000 deaths in the United States are attributed to only one of several types of leukemia in a year. It almost comes down to a toss of the coin of which is worse and depends on how "worse" is measured.
get to the doctor because it will turn worse, and it can have many different outcomes.
knock that person out so you can get yourself out.
Your puppy needs to see the Vet. Blindly giving antibiotics and antihistamines may be covering important symptoms or even making the problems worse. There is absolutely no excuse for a puppy this young to be suffering like this and in such poor shape.
The poor is the poor because they could tax problems, debt problems, or even worse.
