Welcome to icliniq.com.
Cold and sweaty hands and feet can happen in heart failure, anxiety, hyperthyroidism and shock.
Numb feet, which are painful while walking can be due to neuropathy, nerve root compression at lumbosacral spine, or arterial occlusion in legs.
The half closed eyelids can be ptosis, or something else.
I suggest you get the following tests done:
- Thyroid profile.
- ECG (electrocardiogram).
- Serum vitamin B12.
- NCV (nerve conduction velocity) of all four limbs.
- Repetitive nerve stimulation test.
Since when you are having these problems? Do you have any impending doom, palpitation, breathlessness? I suggest you meet a neurologist in-person for proper clinical examination and better judgment.
