I am 51, female & a smoker for maaany years. Is it true that numbness in hands & arms is a sign of lung cancer? It happens primarily when I am vertical, resting or upon waking from sleep. I also have had many bronchial infections over the years & just recently developed a chronic cough. I try ever so hard to quit, using a number of methods, but always fail & give into temptation. HELP ME PLEASE!
Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. I don't think your numbness in arm and hand is due to lung cancer. Because lung cancer will not cause this. It can be due to smoking related neuropathy. Vitamin B 12 deficiencies is common in smokers. So your numbness can be due to this. Get done B 12 level and if deficient start supplement. Also get done chest x-ray to rule out lung cancer and other smoking related lung diseases. Quit smoking as soon as possible. Admit in rehabilitation center. Nowadays good antic raving Chat Doctor.  Consult psychiatric doctor for dead diction.
