Severe pain after an IM injection in arm

Hello Doctor, My wife is suffering from severe pain in her arm during muscle movement after her 4th IM injection (among a coarse of 5 Rabbies injections). She got her injection 11 days before but she still feels a lot of pain during arm muscle movement or while lifting anything from that arm where injection was injected. Can you please suggest what to do in this case. Shall i continue applying ice patches on that area where injection was inserted or should i consult to a doctor.. one more important thing is that during the time when she was getting the injection on her left hand arm, there was blood came into the injection then the nurse tried to apply the same injection on the right hand arm. When about 0.5 ml of injection got inserted then she felt a lot of pain and nurse stopped to insert more injection into arm. Since then the pain started and it didn't fixed. Still she is feeling a lot of pain while moving her right hand arm or lifting anything from that right hand arm.
