Am 24 years old, 6"2 tall and weight about 75 kgs. I don't take any medication. For the past 4 days I have had this dull ache starting from my left shoulder blade going down towards my hands and fingers. My hands also feel hot although am not sure they are. I don't know what triggered it but I have also noticed a pimple on top of my shoulder blade pressure point where the pain seems to be starting from. I also feel a numb tingling in my hands. The night before it started I had a headache.
