...had health issues concerning have an unproportional body, as in too much muscle on one side.

I'm curious as to if there are any negative effects on the body, cause i'm thinking that having too much muscle on one side may put too much strain on the other side of the body.

So tell me about any issues you or your friends have had with being unproportional.

one side of my body is actually a little taller than the other side (like raised shoulder, uneven eyes or something) but it's really not noticable unless i point it out. negative affects? no, not until i hit a really bad backhand 3 years ago, and have had back problems since. though i've been seeing a chiropractor this summer, and regular flex excercises will fix me right up. so, as long as you control your body, like tone down your more muscular side, or tone up your less muscular side (since it is up to you how you'd like your body to be... with hard work of course =b) that should be all right. then again, if you're wondering if there'd be any repercussions, you should consult a doctor.

i'm the same as you, lol my right side is a bit thicker and taller.

if you are talking about your fore arms because your racquet arm is larger than your non racquet arm, that is an acceptable unproportion growth of the body. Its not significant enough to cause any problems except maybe if you are working in some labour intensive career it may cause extra stress to one side to compensate for the other (however one could argue that being in labour intensive work would make you an overall stronger person). Unless you have an actual diagnosis of body disproportion like hypertrophy or hypotrophy its really nothing to worry about.

Not only forearms...legs and shoulder and even abs....yes i know abs (like WTH right?)

I think we are all the same. I know i am. Rite side slightly bigger than left side. Other people sometimes cant tell but i can see a difference including abs.
Shouldn't be any health issues i don't think. Its just the fact that your right side is your dominant side, the side you do all things with such as use a racket, write with, life with etc. i would say its normal.

My mates brother is a bricklayer and he is left handed. Left bicep is about 16 inches or so i think, right bicep is about 12 i think, not too sure. Al i can remember is that there was about a 4 or 6 inch difference (10 + cm difference) which is crazy because its such a big difference.

yea i don't like the abs difference it looks little weird eh

There are subtler difference as well. Your racquet shoulder is probably a bit on the side of overflexible, which has its associated instability injury issues.
