I went to ER for broken ribs (7) and they found lots of other issues that they wanted me to follow up when I was out of the hospital. Most of us with weird symptoms have a list of specialists. All of your symptoms may not be connected to one diagnosis. For joint/back pain, go to orthopedic for images and then a referral to Physical Therapy to help with balance, muscle strength and joints. Visit an ophthalmologist (DR) for issues with your eyes. Switch to a non-processed diet, avoid sugar and aspartame, preservatives, moderate potato, tomato, wheat and dairy. You may notice others that you need to avoid; Mediterranean diet, AIP or Terry Wahls have good recipes. Make sure you get some movement, each day. There are plenty of moves that can be done in bed. Finally, make sure you are staying hydrated and eating enough food - lots of time when we feel ill, we stop doing this and it gets worse. You might request a panel for autoimmune disease, like Lupus, fibromyalgia, MCTD. Diagnosis and meds will help, but diet and movement are huge, also.
