"Terrible service"

Having had months of shoulder pain from a fall and suspecting nerve damage its near impossible to get sensible results or treatment. Referral from doctor took months but ultrasound showed nothing. After being left unable to move or get dressed without help on thursday i managed to get to a and e on friday. Waited almost all day to eventually being sent for xray. No broken bones but still in absolute agony. No treatment offered, cant move my arm ,pins and needles etc ,shaking limbs down left side. The outcome is he reffered me to a bone specialist. Need to wait for an appointment but im now 9 months of pain and this does not make sense or seem reasonable. Surely at this point an mri would be sensible,some kind of pain releif etc. I fell on this arm and think the nerve is trapped or damaged but literally can not get any help. Im at the point id take amputation ,its agony. Please tell me what i am meant to do
