I had a sprained once on my right wrist, not because of weightlifting but because of a 'tukang urut' wanna show off his skill thus dislocating my wrist 
It took literally 1 year for the wrist pain to go away but I didn't do any workout/rehab or take any medication whatsoever. I just bear the pain.

Veins fused? Hmm. I think though that sounds not credible at all it could be due to adhesion, scar tissue and nerve impingement, which is pretty similar to what they wanted to convey. I believe this could be the case, and appropriate treatment is something like myofascial release and the active release technique.

I don't think there are many such practitioners in Malaysia, the closest being Singapore, and it would cost a lot too. The one that comes close to it is a traditional Chinese guy who uses hot eggs and rubbing technique, which would produce some similar outcomes, so no harm giving it a try, it's in Kuchai Lama. Combine the massage with rehabilitative wrist exercise which I'm sure you can find online.

To the guys who do pyramid sets, how much exactly do you increase per set? Generally, I'd add like 2kg for chest and arms while for legs and back, I generally add 10kg each set. Are there some calculations involved? Some would say to increase by percentage according to your 1RM, some say just go by feel?

My right arm is stronger than my left arm, eg. when I'm doing Alternate Biceps Dumbbell Curl, my right harm can pump 10 rep but left just 6 rep only.
Anyway to improve the strength balance for my arm?
TQ!
