Medical info & terms that save lives & improve health

I live in a rural area, where some of my best friends probably tolerate me, simply because of my ability & willingness to read, look up & explain things. Our primary care clinics are ran by nurses, with few speciality physicians available, one day/mth, by referal. Things quickly done in cities are very long trips & big ordeals from Gods county. This app has been a lifesaver, providing info that’s enabled a better understanding of possible health issues, diagnosis & the ability to then discuss & ask questions at the next medical visit. To have some ability to make informed decisions about healthcare. Above all, it’s provided, understandable info that multiple friends have desperately needed & used, after test & treatments were ordered, that gave them reason to choose to give up, cancel appointments & avoid useless efforts, & pass in peace at home. This lil app provided info that has saved lives of those I love, thru understanding terms which in turn provided hope, treatment & cure.

There are things that can still be tweaked, & continually improved, that is always part of any successful endeavor, but it’s a lifesaving lil app already.

This review is very accurate, it’s also part of my grade for school.

The app is extremely easy to use, with the type of one letter there are many options to select from so correct/full spelling is not required. There are many ads if you are searching for words repeatedly. Share words, favorite and simple search allows you to search with parts of the word ex: starts with, ends with. The app does provide an in-depth definition and has hyperlinks for some medical terms used, so if needing further explanation one can easily select the hyperlink for comprehension. I have downloaded and gotten familiar with the app; I also google words/phrases I would like to know more about a lot. So, I will not only use this app for school and work (I work in a Dr’s office also) but also for personal use. A speak feature would make this app perfect!

If you’re find with ads, finding the definitions is easy and productive. However, as someone with erythromelalgia I found the definition very misleading and dangerous because of how misleading it is. EM is known to START SHOWING SYMPTOMS IN ADOLESCENCE. Not in people middle age. Another part of this is there’s a higher mortality rate due to suicide so I’m not sure how many of us MAKE IT TO MIDDLE AGE. EM is not something that can be planned. Em can either progress rapidly over weeks/months or steadily over years. I found the part where symptoms generally go away with cooling and rest to be infuriating. As there’s a reason why MAYO CLINIC HAS AN EM CLINIC. Because after the gabapentin, the ketamine compound, Botox, and then the nerve blockers there’s not really much left to do. I have to deal with ignorant doctors and nurses who will tell me my exercise induced flairs can BE FIXED BY EXERCISE when it puts me at risk for nerve damage. Please stop contributing to the idea that because it’s not cancer or liver failure, EM isn’t severe. Because it is. And many of us commit suicide because the pain is so bad.
