Hello. So about 3 months ago I started having a sensation all over my body that can be described as crawling on my body. I also have back discomfort on the left side of my mid and lower back. In addition to this, the left sife of my back feels numb when I move into a certain position. Not sure if this is related to my symptoms but my hands and feet sometimes feel slightly numb. It will be greatly appreciated if someone could help me.
