in your case two of the most predominant issues are radial artery occlusion (RAO) and radial artery spasm
Radial artery occlusion occurs when a clot forms in the radial artery that blocks antegrade blood flow. This clot is thought to be from vessel irritation or injury
during sheath insertion and removal, which leads to spasm .
consult with your doctor , increase your drugs , you can use warm water bag on local site ( pain relief and will decrease spasm)
if pain persist then do in radial artery color Doppler for assessment of radial artery thrombus
