If you do a google search you should be able to find Michelle Rainey's website.I saw a clip of her on Urban Grower and she has crones and uses a specific strain to relieve her symptoms,I dont remember it off hand but I think it was an Afgani.Check out Granny's post on this thread,Ive looked up the links she had to MS and weed,pretty outstanding stuff.Good luck man,a dear friend of mine has crones and Ill try to get some info from him that I can pass along,good luck and take care brother.
