Hurting and now being harassed.

I hurt my back at work and immediately my boss accused me of lying telling me that I was over exaggerating and that I was just trying to get workman’s comp which was never the case. I have always been a hard dedicated worker so when I pulled the main muscle in my back I’ve been in extreme pain. I went to the doctor he said to do very minimal activity and when I told my boss he started yelling and telling me that those don’t apply (which they did) and he told me to show up Sunday night or I lose my job so I’m in pain and go to work and I start to throw up from the pain so I finishing my 12 hr shift and go home immediately to bed hoping to make the back spasms lessen but woke up in extreme pain crying because I can’t breath so I called the office and told them I need to go to the doc again so I just went today. He told me no work until I get seen again (two days) and to take strong muscle relaxers (which only took the spasms away for three hours and they were back worse then ever) and told me he thinks I need PT and I got a shot in my back for the inflammation but it didn’t help my back but it did take the pain my whole body was experiencing from the constant spasms. Well my bad who I work with goes to work and my boss is bitching and telling him I must be faking it and that I’m just wanting to get workman’s comp and that I am being a baby. Note that before all of this he screamed and cussed and talks shit about me to all the guys I work with and he has been harassing my boyfriend complaining about me. Now I have to get out of bed (which is what the doc told me not to do) and go to the office and deal with this. I’m so stressed out right now and I’m so much pain. 😭 I can’t believe I’m being bullied and my job is being threatened because I accidentally hurt my back at work 🤕
