I've been feeling vibrations in my right hand for the last month. Although I can continue working, it's irritating. I take Amlopin 2.5 and Concor COR 2.5 regularly for high blood pressure, and I have an acidity problem.
A vibration or tremor in the hand can be due to various conditions, some of which may be related to your existing health conditions or medications, while others might be unrelated. It is best to get checked by a doctor to know the cause and get the right treatment. Until then, avoid overusing the hand, get good sleep, and do gentle hand and neck stretches.
