The main difference between the two is the causes of these gouts. When you say gout, this is normally caused by uric acid crystals. When you say pseudogout, this is caused by calcium pyrophosphate dehydrate crystals, also known as CPPD.
The symptoms that people experience when they have these conditions are similar, but people need to get themselves diagnosed so that they can get the proper treatments that they deserve. People who have gout may experience attacks of pain from time to time. Some would last for about half a day. The attacks of pseudogout are usually longer.
