Hi,Dear,Thanks for your query to HCM. Dear I read your query and reviewed it with context to your query facts. I understood your health concerns and feel Concerned about them. Based on the facts of your query, you seem to suffer from- Neurogenic TOS on right with Venous TOS mostly caused by Congenital Extra Cervical Rib with / or without Extended Transeverse Cervical Processes with / Scalene Anticus Syndrome and Pectoralis Minor Syndrome. Cause of this- AS explained is the narrowing of the Thorasic Outlet-caused from Extra Congenital Cervical Rib/Scalene anticus / Pectoralis Minor with Long Transverse processes of Cervical Vertebra,which causes Nerve(Brachial plexus),Subclavian Arteries / and Subclavian Veins. -Cause of the bulging Right hand Veins - Is due to the Venous Obstruction caused from Compression by Scalene Anticus Muscle head,pressing the Subclavian vein at the Thorasic OUtlet to compress against the first / or the Elevated floor by the congenital aberration by Extra Cervial Rib on the right hand side. -Cause of Numbness in right hand -is also caused by the accompanying brachial plexus nerves around the Subclavian Veins on right hand side. -Cause of the numbeness on Left side- is also due to the nerve injury by compression of the left brachial plexus from extra cervical rib/scalene anticus muscle / or pectoralis muscle or the reduction of the costo-clavicular space from fracture rib. Investigation- CT NECK / X-ray Neck/ MR angiography(MRA)- would fix the diagnosis with Color doppler study of the left and right arm arteries and veins and with Second Opinion from Surgeon.
