Hello,
I have studied your case.
There is possibility of transient ischemic episode leading to pain in your arm and eye.
You may need clinical examination to confirm neurological weakness, BP and other vital parameters.
Another probability is due to compression of this
nerve root there is pain radiating to your arm.
You may require
MRI brain and spine.
For these symptoms
analgesic and neurotropic medication can be started.
Till time, avoid lifting weights, you can consult physiotherapist for help.
Physiotherapy like
ultrasound and interferential therapy will give quick relief.
I will advise to check your vit B12 and vit D3 level.
