I've got a borderline crippled right knee. Two knife scars on my left hand, one on my left forearm, one on my right hip and another on my right shin. I have asthma, celiac disease (no wheat, rye, or barley, or most oats, or it causes intestinal damage), a seizure disorder, I don't absorb sodium or potassium properly, so I have to supplement both...the sodium issue also generally means I am dehydrated. I have significant allergies to most living animal dander, wasps, hornets and yellow jackets, and serious allergies to cat saliva and cockroaches, as well as allergies to molds, spores and mildew, pollen and the like. I have poor eyesight, though correctable with rather high prescription glasses, and an astigmatism. I am addicted to caffeine, and have a high tolerance for most pain medications, due to chronic pain and migraines, and the tolerance developed from treating such. Certain plastics, namely those used in food service gloves which are not latex react to my sweat by melting and cause nasty burns. The same odd chemistry of my sweat causes shoes and clothing to wear out more quickly than usual. I am underweight for my height, though in rather good physical shape despite such, though the crippled knee has hindered maintaining such somewhat. I have hypoglycemia sufficient that a doctor has actually stared at me in shock after a glucose tolerance test, unable to grasp how someone with such low blood sugar could be outside a coma, much less conscious and only mildly dazed. My blood pressure is fairly low, and has been known to drop so low that I was mistaken for dead when merely sleeping by hospital monitors. I also have some mild eczema problems. My left knee has permanent cartilage damage, and that's my good knee.
Overall though, only the knee issues, seizure disorder and migraines are more than a tolerable annoyance, so long as I take care of them properly. The asthma can be concerning at times, but is controllable, so long as I keep myself in good shape. Similarly, the knee issues are tolerable so long as I keep my brace and cane handy, and pain medications for the chronic pain caused by such. The migraines and seizure disorder aren't currently effectively controlled, though we're working on that with my doctors.
