My spine and neck pain refrains me from work. What should I do?

Hello doctor,

My main issue is spine pain accompanied with neck pain (disc is dislocated). It gets worse when standing up from a sitting position. When I get up from floor, I feel lightheaded. Sometimes it is that intense that I faint for a few seconds. While sitting in a car, I lose vision sometimes for a few seconds. Even walking is suffering as I need to rest every few steps I make. When laying in bed, I feel normal. My blood pressure is lower than average and I often have strong acid reflux. Once I had terrible stomach pain accompanied by acid reflux and vomited dark acid. On some occasions my chest is burning as well, even when laying down. Besides disc dislocation I have been diagnosed with one of the heart valves to be loose, and with irregular slower heartbeat. Could you explain to me the cause of these issues? Are the symptoms related to each other or could it mean something else besides that?

I do nothing because the pain makes it impossible to do anything as I stated I have to rest every few steps. Before this injury, I was lifting heavy things and driving a truck for 30 years.

I have no physical activity anymore, the pain is unbearable. I have been having issues for five years. All I do during the day literally is laying in bed, then sitting in the kitchen and outside in the yard then going back to bed. I did try to perform housework but it made the pain even worse. Please help.

I take some pills to calm down the acid reflux and pain killers occasionally.
