Hello dr,my problems started with strong headaches in october last year,then pain was spread to my middle back.that pain was very long time just in one point,and was so sharp like a nife in my back.After pain from middle back was spread to the neck,head(headaches non-stop from october) and down to lower back (affect my legs,they are weak)I can walk only with crutches.My shoulders and legs are heavy,feel like I would walk 3 miles distance.From last week I recorgnised ringing in my both ears.Thank you for your answer.
