Cortizone shots are TEH SUCK!!

I have severe hypermobility in my shoulders, this means the tendons and ligaments arnt tight like they should be and my arm is realy loose and subluxes (semi dislocates) very easily…like with the push of 1 finger easy. the sht is suppose to help with the swelling that is pressing on the nerves in my arm…iv very painfull. But my dr. is a fuck tard, they havent done an MRI yet and he wouldnt give me any pain killers, even though i repeatedly told him i cant sleep due to the pain.
