Hello, I’m Wondering If You Might Have An Idea Of

Question : Hello, I’m wondering if you might have an idea of what the heck is going on with my body this week lol, so backstory first.. I’m a 28 y/o male in good shape, I’ve had really painful tmj on the right side of my body for years and I think it keeps the muscles on the right side of my body kinda tight also, so I’m always trying to do something healthy to see if it might help that, so about 2 months ago I completely quit drinking all alcohol and caffiene cold turkey, the first week I felt horrible I think because of the lack of caffiene ( I work long hours). Since then I’ve always felt pretty normal and mellow/ clear minded, I sleep really good too, and my skin is a bit clearer now, my tmj still hurts like crap tho, so this week for no reason I just started feeling horrible and really weird again, I was shaking all day, with a fever, and I felt really cold at the same time and was sweating a lot for 2 days, and my lower right abdomin had a tiny bit of tenderness for 1 night, and those were the only symptoms, it didn’t feel like I was sick with anything, i had no runny nose or cough or vomiting or anything, it just felt like my body was having what I hear people describe as horrible withdrawals, now today I’m at work again walking around and I still feel real weird but good also, so anyways idk if anyone can make anything it of this weird story of mine but if you can than thanks!
