Perhaps after receiving only four injections in about the same number of months it is too early to consider the meanings of these concepts I happened to stumble upon recently on one of those "pubmed.ncbi.nim.nih.gov" sites but since experiencing no significant benefits I am wondering if there is any reason to keep submitting myself to these barbarous treatments, especially if I fall into this category of unlucky patients. The phrase "treatment-resistant" may also apply here, just another way of saying "it ain't working"! Just four shots so far but the injections themselves are getting progressively more painful and so is the post injection pain. I almost lost my mind after my last shot (12/23/2022). I have an upcoming appointment with a different provider coming up in two weeks. Needles, ("sharp sticks"😉 and foreign substances injected into the eyeball can't be good in general. To me it is not too different than leaches or blood-letting considering that in the not too distant future stem-cell/gene therapy will maybe even totally restore vision. I don't think I can do this even one more time let alone for years - seriously. What is taking so long with the research? Any guesses?
