The 31-year-old's latest outburst follows his appearance as a substitute in Albion's goalless draw at Stoke on Saturday.
Odemwingie has made only four outings from the bench for the Baggies since his move to QPR fell through as the transfer window closed in January.
The Nigerian famously drove down to Loftus Road on January 31 but was barred from the stadium and was forced to return to West Brom before hitting out at his club in a series of tweets.
He now appears to be unhappy with his situation at The Hawthorns once again and was busy tweeting on Sunday afternoon.
Odemwingie tweeted: "Keeping me on the bench now is worst than what they did on the 31st. New advisers told me to take say its all my fault cos its better or me.
"If they like they shouldn't even give me 10 mins to play. Threatening to ruin my career? Career I closed already last summer? No harm to me.
"Want to treat me like an average player. The abuse and praise I get is it average ? So get some extra from me too.
"Former Albion sporting director in the presence of the new and Manager apologised to me in private. Publicly not good ? Come under my cloud.
"Drive was lunacy ? Missing in the training section that day also lunacy ? They forgot to complain about that though cos they knew were I was.
"Things have almost got back to normal till Peter spoilt it again. What's normal ? We see things differently obviously.
"Has anyone seen me give interview to clubs website for a year now ? What about an interview in match day magazine ? I am on my own there.
"Was ready to give half of the contract there and earn less to make it happen. Forcing a move really is when u want to leave 4 free."
