If you quit smoking you can do the same for drinking. It is toxic to the liver. That needs your attention. If you drink because it relaxes you perhaps a different approach would help and reduce anxiety or stress. The lymph nodes are probably just working overtime to keep the drip in check. This is the time of year. I've got pn.drip that could choke a horse

, with a sensation of fullness in the neck area that's allergy related in my case

. I do some facial massage to improve lymph node function/flow (chiro performed when I had sinusitis) and gargle with salt water, antiseptic mouthwash.
Regarding the numb sensations of the hands and arms; is your work area ergonomically correct? Improper posture can contribute to neck stiffness. Doing so much work at the computer-check your station. Gentle range of motion stretches for the neck may help reduce and prevent the stiffness. If you lean on your elbows enough, that can cause the hand & arm sensations you state. Circulation in the limbs could be affected by improper body mechanics, lack of ergonomics etc. The wrist bar-rest helps me and I changed from a mouse to a rollerball back to a mouse with a center wheel to scroll. I'm sure you have all that and more-a once over couldn’t hurt. Reduce salt intake and fast foods ^ in sodium. Perhaps focus on stress reducer tailored to you is in order. Brisk walks. At work take a few moments in intervals to stand, stretch, stroll even if it is brief could help. I mean a conscious effort! Be Well, G
