After 3 days of intense physical activity moving my elderly mother and clearing out her home I developed a headache and mid back pain
. Bending over
, coughing, sneezing, etc causes an explosion of pain in back of head that takes a few minutes to ease, leaving dull headache. Never experienced anything like it. Saw doctor who ordered CT scan which was normal including sinuses. However the next day my ears became full, light buzzing, amplified "in a barrel" sensation.
