Insert the needle at a 5 to 30-degree angle and slowly push the needle forward subcutaneously for 1.5 cun towards the knee, parallel to the leg.
If the problem is distal to the point (for example, on the foot or toes), insert the needle in the opposite direction towards the ankle. In this case, move the insertion point away from the ankle slightly so there's sufficient room to push the needle forward without hurting the joint.
