Hello. This is a touchy subject for some due to beliefs they have about marijuana. My experiences are hit and miss and likely due to the strains I have tried. I use indica or hybrid-indica because they are night time strains and help induce sleep. The strain names that I find most helpful for CRPS so far are below and can be read about with effects with Google search of strain name and Leafly. I typically use flower but also use the jello-style edibles for maintenance during the work week after work because smoking is not an option due to fear of not being on point the next day for work.

Chemo
Cereal Milk
Tasty Trees
Ken's OG Kush
Rainbow Mints
Superglue

These are strong THC content 25-31%. They pack a wallop, these are one-hit strains to be effective. Depending on your comfort level use what is needed. I typically smoke 4-6 times in a sitting for maximum effect and wake up the next day in better shape pain-wise. Never truly rested due to CRPS but this regiment helps, and for me personally they are used close to bedtime because I want my family to have limited exposure to this way of pain relief. However, smoke, lay in bed and relax works quite well in the dark. Focusing on your body, stretching and having the CRPS pain taper down significantly.

Hoping you are well.

Wishing you the best.
