Help obtaining medical card

Hey there. First off, this isnt BS, im not trying to get a medical card just because I want to smoke, I actually have been told that I should get it, and I do not smoke at all! Anyways...

I have very bad headaches, and naseua a lot. I also have really bad joint pains in my ankles and knees, and when I run I have bad pains on the right side of my hip. For the past year or so I have also been having cases of insomnia and it has been effecting me in school and i do not want to get put on academic probation... I just moved to CA about 8 months ago, and I cannot get my medical records from my doctors office in HI because they are not helping me at all.... I have an appointment to meet with a medical marijuana doctor here in San Diego on wednesday, and I am going to tell him all of the things I have stated above, but I was wondering if anyone else had helpful information for me.. I am still trying to obtain my records from my old doctor, but the HI medical system just sucks... Like I said i am not BSing, I am really looking for some help. If anyone could help me on what I can say to the doctor, or anything else that may help me would be great. Thanks!
