Hi there. probably nothing but my head feels uncomfortably heavy, like there is pressure coming from all angles, and neck is straining (no sharp pains or anything). minor ache all over. could be stress or lack of sleep (have done symptom checker) ?

Headache: These are usually symptoms of muscle contraction headache. The muscles that support your head and neck tighten and then begin to spasm. It can start due to fatigue, stress, strain and even an early viral infection (minor aches all over). Helps to rest your head, apply ice to the back of your head for 20 min(relieves the spasm), then remove, use tylenol. If it worsens,you will need to see a doctor
