Is this Sciatica? I've been in pain a long time and it worries me.

I'm currently 25. About three years ago I was carrying a 10 pound bag of dog food, next day I could barely walk. This is not an unusual task for me so I was shocked...My GP said I was fine the first day I hurt my back so I made it worse by continuing to do activity and exercise. About a week later I couldn't move and went to the ER. I've had an MRI and I had 3 bulging discs and 1 herniation. Ever since then, the right side of my lower back has been in agony.

More info I forgot to add:

I feel like there's a lump near my tailbone? It's movable like a fatty bit. Feels weird to move it but doesn't hurt. But the pain I experience is so hard to pinpoint. I feel it almost in my bone? Or like... The centre of my back, in the flesh. It radiates like a rope all the way down my right leg into my foot. I have a lot of trouble standing, and when I lay down certain ways I am in agony.... Cold and rainy weather makes the pain worse. Same with too much humidity.

I'm a little bit anxious, so I always think the worse eg. Aortic anyeurisms or something stupid like that. I can't really afford to go to the doctor often so I just wanna know... Does this sound like sciatica? Am I laying awake at night thinking I'm dying for no reason?

To shorten things, the symptoms I have:

- Pain in lower right quadrant of back, near tailbone. Feels like it's in the bone or flesh. Very deep pain.
- Pain extends down right leg into foot. Increases due to cold, rain, humidity. Sleeping wrong. Can't sit or stand in certain positions.
- Occasional uncontrollable shakes not caused by low blood sugar. Often from 8-hour work shifts standing.
- Pain makes it very hard to sleep or eat. Sometimes feel nauseous due to it. Causes some depression and anxiety.
