Pain and frustration

So I have had virtually no pain for about 2 months. Something happened over the weekend, my back muscles went weak again.... Not sure what happened. I hurt If I sit or lay down. Super stiff and hurts to stretch. Plus every time I get up to walk I look like I have a stick up my butt, until I get stretched out... Can't sleep so I took a lortab last night. Ugh I do not like the feeling... I took it right after dinner. It makes me sick to my stomach and gives me a head dizzy feeling like I had some alcohol. Me no like. It wore off at1:30 and didn't sleep much after. Now onto the heating pad. :( why oh why:( I need to work but this is so embarrassing and frustrating and painful. Lord help me please !
