What Causes Chronic Chest Pain Post Chest Pains?

About 8 weeks ago I had several incidents of chest pain and lose of arm muscular usage in both arms for a few seconds each. I ve since had a heart cath showed to be normal. I had a brain CT scan 2 days age which also was normal. The main complaint I have is a severe continuing headache since the attacks from 8 weeks ago. I ve missed a couple weeks of work due to this headache. I m 53, overweight an ex-smoker, high blood pressure and high cohloesteral. I m really wanting someone to tell me what is happening.
