Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Given the lack of nasal congestion it is unlikely to be a sinus headache. It looks much more likely to be tension type headache, which is a very common benign headache. It is often associated with anxiety and in my opinion that is an issue you suffer from as well. Those symptoms of lip and fingers tingling, chest tightness you describe are commonly found in anxiety and that seems to be the most likely cause, in particular given normal ER test results. So I suggest relaxation exercises, activities like yoga and only over the counter Ibuprofen for headaches. If symptoms persist anti-anxiety medication like Amitriptyline (also used for headache prevention) may be considered. Hope I have answered your query. Let me know if I can assist you further.
