I was talking with my boyfriend today about some persistent medical issues he's been having for quite some time. About a year and half ago, he began having problems keeping balance, or walking in a straight line without drifting off to the side. Around the same time his sight would become blurry if he looked to the left or right quickly, and then he start having serious knee pain and also stomach pain. He also said his fingertips would bruise easily and his toe nails also. Til this day his stomach and knees are a big problem. Doctors have ran a few blood test on his stomach, only once it came back abnormal, so they have not looked more into it. He plays football so his trainers told him the knee problem was just tendonitis, but since it happened at the same time where everything else was going on in his body, he feels that its more than that. I was just wondering if you all have ever heard of anything close to this? Or have an idea of what it is?
