Pressure clamp for relieving a headache

A medical device configured for exerting pressure on a person's fleshy part of his or her hand between the thumb and index finger for relieving a headache, the medical device comprising:

• an upper arm and a lower arm pivoting together at a first end of each arm at a point distal from the fleshy part of the hand;
• a thumb screw turning a shaft passing through a bore in the upper arm to threadably engage threads in the lower arm so that turning the thumb screw causes the upper arm to move downwardly to close a gap between a second end of the upper and lower arms with the fleshy part of the hand squeezed between the first and second ends;
• the upper arm having a downwardly descending leg at the first end, the leg terminating in a ball engaging a socket in an upwardly ascending leg at the first end of the lower arm;
• and
• a bottom surface of the upper arm second end having a convex surface and together with a top surface of the lower arm second end adapted to engage the fleshy part of the hand in a tight configuration when the thumb screw has depressed the upper arm.
