Hi,
Welcome to the ehealthforum and I am glad to help you out. In view of the symptoms, it seems less likely that the symptoms of chest pain are related to the numbness in the hands.
Itâs good to rule out diabetes by getting the blood sugar done as itâs one of the commonest causes of neuropathy (damage to the nerves) which can result in the numbness of the hands.
The other common entity is carpal tunnel syndrome in which thereâs compression of the median nerve close to the wrist and for that hypothyroidism is one of the important culprits and thus getting the thyroid hormone levels checked makes sense. Please get a chest x-ray done to look for the cause of chest pain.
I must tell you that making an online diagnosis is extremely difficult and thus please get yourself physically examined by a physician. I sincerely hope that helps. Take care.
