Sounds like you want to quit. Another option is to inject the delts, and see how your body responds to PIP there. Quads are just painful for some guys.
Also you might be having a reaction to one of the solvents in the steroid solution. Ethyl oleate is the common cause. Its not normally used in 250mg /ml test.Normally used in 400mg or higher concentrations to keep the steroid in solution. Some labs use it for everything though. Gives intense pain for some guys.
