You are having physical complaints, so seek help from physician. If you are having anxiety and tension issues then consult a clinical psychologist or psychiatrist.

Consult a General Physician for a general checkup.. That might be able to do the  diagnosis.. And, if you feel that some incident or someone is bothering you and you haven't resolved it, it is better to seek a professional support to overcome this problem..
