sorry to hear about your condition(s). First of all, I am not a medical professional so any advice I give you is just based on opinion.
It sounds like you are having a bad time. I am not familiar with Prolotherapy, and have not encountered it, so I can’t really pass comment on that. With respect to your suspected RSI injury, you should 1. try to find a good Physio (it can be hard to find a good RSI one, but its probably worth spending some time hunting one down. Some Physios do acupuncture too and can perhaps advise you in this regard. I have not had acupuncture treatment specifically for RSI.) 2. Like you suggest, ditch video gaming completely, it’s not worth risking your future health for. They are very addictive (from experience), and its a good idea to break free. They are going to take a large toll on the health of generations to come. 3. When choosing a physical activity, I really recommend doing non-impact activities for strength and conditioning especially if you are prone to injury (like I seem to be, I have had more connective soft tissue, ie ligament, tendon etc injuries than I care to remember, indeed I’m still recovering from a sternum strain from last October!). Other good low impact fitness activities include cycling, kayaking, and working out on elliptical type equipment. Avoid weights until you are pain free. Keeping fit is a good thing to avoid injuries though.
You mentioned pain whilst typing, but didn’t really elaborate about when and how you are typing. You need to be sure you have good ergonomics whilst typing, its very easy to not have good ergonomic posture which can easily cause an RSI condition to get worse. You should consult an Ergonomist or again an informed Physio may be able to advise.
You should also try to not fixate on an injury eg. RSI, the stresses involved can make you apprehensive and more prone to tensing already tight and sore tendons etc.
My advice would be to find an activity that doesn’t involve causing pain to your existing injuries and focus on that activity instead. This will give you time to heal up your injuries.
You may also want to review you diet and make sure you are getting a good balanced nutritious diet. This will also help your body heal. Your GP may also be able to advise whether taking NSAID painkillers may be beneficial for a protracted period, you should talk this over with your GP first.
Keep in mind you are only 21, and as such you have the advantage of a faster healing capability than those of us who are older.

I can sympathise. You are in a situation similar to how I was before I decided to leave my job due to RSI. Your 10 year run with RSI will likely not clear up quickly. Mine is still with me some 4 years on from leaving my job, and can flair up badly withing a short period of time when using a computer. I’d certainly chew over all the options before choosing to leave, including employer related ones like the possibility of changing career with them away from the equipment causing you to have a problem. If this comes to a dead end, then chew over with your manager, managers manager, HR. If that comes to a dead end, talk with an employment lawyer and see if you are being discriminated against based on your disbility – even their advice may be useful. If all else fails and you can’t resolve further explore the leaving options including early retirement, severance payout, personal injury claim etc. and see what one works best for you. ps. document well all interactions with your employer where they are not being sympathetic. (Emails I believe are not good enough in any claims process.)

Sorry to hear about your injury. You are in a similar situation to myself. I reached the stage that it was no longer tenable for me to continue in my field of work. You are correct in that you get to the stage that every input device causes some pain. (Have you tried mouseless cick software? touch screens? roller mice?). I managed to prolong my working life with employer allowing me to do my job through a graduate employee for about 18 months, at which time they were fully trained to do my job. Not the most secure thing for me, but it did help me to continue to work for a while.
Beyond that you really have to ask yourself serious questions about how much the job is worth to you and your personal well being. I knew I’d need my hands/arms to function properly in any other job I’d do, and wasn’t prepared to let them get any worse in order to prolong my employment. Choosing what else to do was very challenging since just about every job out there involves computer use. I ended up choosing to work for myself (maximum flexibility, and I get to dictate work load) and combined an interest I had in photography with a picture framing business.
The framing business keeps me busy and allows me to do non computer related work. It’s certainly not quite as lucrative as my previous computer related work, but it’s better than sitting in pain over a computer every day. Choosing another line of work and retraining can be one of the hardest decision you will ever make, so take your time and make the choice that it right for you.
