"I cough with all the vape pens I’ve tried. I smoke different stains a day to deal with my MS. I was just diagnosed with frozen shoulder. What is the strongest pain, and best for sleep?"
It really depends on your constitution and what ultimately works for you. With cannabis as you probably know, everyone reacts differently. I can point you to some recent articles we have written on this topic:

Also, have you tried any edibles rather than vaping? The pain relief typically lasts longer with an edible at around 4-6 hours.
Lastly, there are some great topicals on the market which may help soothe your shoulder. I love Sweet ReLeaf and Flower Power.
I am not a doctor and this represents my opinion only.
