I had a 3rd degree vaginal tear giving birth 11 months ago. i am unable to have sex due to the pain. what is still causing the pain and what can i do?

you need evaluation: As it may be from scar tissue or nerve entrapment, you may be abve to be treated with creams but u may need surgical revision, please see your gyn and if your gyn does not feel comfortable treating it or doing the procedure u can be referred to someone who specializes in doing that like at your local university med school center.
