So the left arm is like better today, yesterday it was completely useless when the elbow was > 165° or <15° and even stuff I just use hand muscles for I couldn’t effectively use cause I often couldn’t hold the arm at the right angle to get the hand position right. Now I can’t apply any useful force in those orientations but I can ie two-hand swing a pickaxe where the left arm isn’t really applying power just holding the swing straight
