When I Was 21 I Woke Up At The USC

When I was 21 I woke up at the USC Medical Hospital 28 days after a car ran into my motorcycle head on. I was placed on a bed of ice for 7 days to reduce the inflammation. In the last 42 years I've taken 100 mg Dilantin more than 45,000 times to help me with my seizure disorder. Besides that through a biopsy at USF I now have Temporal Arteritis Syndrome.
A few years ago I have tried different types of marijuana that have assisted me. However, I've been told that there are certain strains of Marijuana that could become more helpful with my issues. Since I have such a problem with processing decisions of what to use has become overwhelming difficult deciding what Strain to use.
Any suggestions would be appreciated.
Thanks
