Arthritis

Can anyone tell me if you have RA or any type of arthritis and what exactly it is that you feel? For months I’ve been dealing with body aches and random parts of my body will start throbbing for a few seconds and then goes away. Sometimes sharp pains. More so in my arms and calves. My neck hurts a lot sometimes feels like it can’t support my head. I also get pain in my mid back sometimes. I plan on getting this checked out but I just wanted to research a little more. Also I was diagnosed 2 months ago with pericarditis (inflammation around my heart) not sure what caused it but around that time I was also having all of these symptoms the doctor prescribed me colchicine which is used to treat gout and inflammation? it actually made my symptoms 10x worse I felt like I was hit by a truck had to stop taking it.
