Hi,
thank you for providing the brief history of you.
As you mentioned you met an accident in 1993 and had surgery done also, the type of surgery to know is important. If any plate or screw is present it may lead to irritation to the
nerve and may give such symptoms. How is the strength in your upper limb .
This symptoms can arise due to even because of the nerve getting trapped in its course or may be in the
cervical spine region, for which you may need a
MRI /
CT scan. Which can help us if any nerve getting trap due to disc lesion.
May be you need some neck and upper limb strengthening exercises post that your
numbness issue will come down.
You can even take guidance from a physical therapist what exercises can be performed and he will surely assist you.
Also, getting once checked by a cardiologist and heart check will be on a safer side.
Prevention is better than cure.
For more query if you have any you can contact me directly.
Regards
Jay Indravadan Patel
