My Husband Has Parkinson's. He Has Rigidity And Bradykinesia. Not

My husband has Parkinson's. He has rigidity and bradykinesia. Not sure if that is important to this but thought I should disclose. He has complained about left groin pain. He has a hard area in the upper thigh/groin area. And the hardness seems to extend down into the left leg. He says the pain seems to move around. Last night in the lower abdomen and tonight in his lower back. Do I need to take him to the ER or maybe just the family doctor?
