I am experiencing numbness or tingling (time frame: gradual onset) (side: one side only) , shoulder pain, back tenderness to touch, aching muscles and foot numbness.

Varies: There are multiple potential possibilities. Numbness suggests possibility of neurological cause. There also can be more than one cause. It is fairly rare, for example, to have foot numbness and shoulder pain have the same cause. Consider being seen for a thorough evaluation Serling a specific diagnosis. At that point, treatment options can be discussed.
