I'm not really sure why but I seem to have weak knees and even worse wrists, which actually hurt sometimes after leaning on them, etc. Also for some strange reason my ankles seem to crack randomly, like when I'm walking or jumping they will crack. I'm 18 so I was figuring this wouldn't happen just yet. Any suggestions?
I must confess i have no clue on possible causes of these, but it seems to me you need to see a doctor for guidance before you can embark on any strenuous exercise regime. most of us have to in order to avoid serious injury.
Increase your water intake and leave the sodas alone.
Weak ankles and knees come alot of times by abusing them by wrong movement.
But its impossible to give advice jusy out of the blue. But what i can say is. Criticly look at your movement. And look up on youtube and google how you should walk and move.
If you are experiencing creaking and cracking in your wrists, knees and ankles at 18, the first thing I would do is find an experianced doctor who know what they are looking for when it comes to Rhumetoid Juvenile Arthiritis. From what you are describing (or what little you are describing) it sounds like the cartilidge between your joints is week and the Sinovial sac (fluid around your joints) is low on fluid - a very bad thing. Conversly, having too much fluid is also a very bad thing.
Seriously, find a good Doctor and have it check out. My Daughter was diagnosed at 3, this is not something you want to mess around with.
no worries, just make sure that your doctor is familiar with JRA and the symptoms otherwise, they may blow it off as "growth platelete development issues". I will not lie, the tests you may have to endure are painful, but if it comes back as JRA, the treatments --such as cortisone shots, and pills, will make your life so much more tolerable and easier for you to workout. Infact, they will encourage you to workout and give you specific exercises to do for each area that will help buil the muscles and tendons around the joints.
Good luck, I hope it works out for you.
