Been having a lot of pain in all my body for 3 weeks along with dizziness. from the past few days finding it difficult to sleep?

Generalized pain : With symptoms that have persisted this long, I advise that you seek medical attention as soon as you can.

Dizziness-insomnia: Vertigo, dizziness, tinnitus, and hearing loss are typically associated with inner-ear diseases as opposed to central nervous system (CNS) diseases. Migraine is more prevalent (10%) than Ménière disease (< 1%). About 40% of patients with migraine have vertigo, motion sickness, and mild hearing loss. Therefore, differentiating migraine from primary inner-ear disorders is sometimes difficult. Neurol

See your doctor: Your symptoms are varied and seem to be progressing now to affect your sleep. I recommend you schedule an appointment to talk about your symptoms in depth. You may need to have some blood testing done. Stay hydrated with water, and be sure to eat healthy foods, including lots of fruits and veggies. Good luck.
