<bot>: Hello! Thank you for asking on Chat Doctor! I read carefully your question and would explain that your symptoms may be related to a viral infection. A metabolic cause could not be excluded. Have you measured your blood pressure during the last days? I recommend consulting with your GP for a careful physical examination, a resting ECG, and some blood lab tests: -complete blood count- inflammation tests (PCR, sedimentation rate, fibrinogen)- fasting glucose-kidney and liver function tests-blood electrolytes. Regarding the neck pain, it could also be caused by a viral infection as well as the wrong position during sleep. A cervical spine x-ray would be necessary to exclude a possible cervical disk disorder, which may trigger neck pain and some other symptoms. Meanwhile, I recommend taking plenty of fluids, carefully monitor your blood pressure and have some rest, avoiding straining physical activity. Hope to have been helpful! Best wishes,
