The atenolol is a beta blocker and the reason it causes 'frostbite' is due to the effect on peripheral circulation which is decreased by the atenolol. So I would expect your pain to be worsened if there was an element of ischaemic disease such as peripheral vascular disease.
Simple neuropathic pain is a nerve related issue and drugs that can help would include amitriptyline and gabapentin. Neuropathic pain can be caused by disease such as diabetes or be due to vitamin deficiency. Proper evaluation needs to be under the care of a neurologist to rule out reversible causes. However for some people, an underlying cause can never be found and so treatment will be symptomatic.
I would suggest that you see a vascular consultant for a review of your blood supply to feet.
My MD said it wouldn't cause this to my feet and hands, but I am very sure it did. I noticed my feet and hands were white and ice cold inside my home , and then when I went for a walk ona cold day with double socks and winter boots I ended up with frostbite .
Would there be something else I could take to slow my heart beat down without this type of side effect. I am already on Amit. and Neurontin and Cymbalta.
There are other drugs which either slow heart rate, or decrease blood pressure. The type of drug that you need should be prescribed by a cardiologist and you should have a full review of your circulation.
If you experienced color change of your hands/feet more regularly then you should be investigated by a rheumatologist for Reynaulds disease and connective tissue disorders.
