I've Been Experiencing Pain In The Right Side Of My

I've been experiencing pain in the right side of my body for months now. I've got a constant dull headache too also on the right side. Most of the pain is dull & in different areas on the right side. In my groin, down & around my thigh and now in my knee a bit. Plus dull pain in the right side of my neck, my jaw & in my ear. I've seen a chiropractor & no relief. Not sure if I should see my primary or go to the er or what. Have had a blood clot before in my left lung but the pain is dull, there is no swelling or discoloring any place. I just don't feel right.
