Hi Kim, what concentration of CBD and THC are you using?Last year I had an extremely tight right leg that caused a contracture. My knee would not straighten out. Neuro at Mayo thought it was a knee problem and mechanical. Went to the best ortho group in Florida and they did MRI/Xray and even gave me a cortisone shot to see if it would improve. They said my joints were perfect and referred me to PT. The regular PT couldn't help much but the PTA, who was also a licensed massage therapist, did massage on all the muscles around my knee as well as my calf and thigh. After my appointments were over my "contracture" improved about 60 percent but I still had pain. I started self massaging, after a hot shower, and using THC cream as the lubricant. I followed it up with magnesium oil and coconut oil.
Today I still have pain but my leg now can straighten to about 90 percent. I make sure I do ROM with it and massage it every day. Also going in the pool and walking from side to side helps.
I don't have foot drop but I do have cramps in both calves. Just make sure not to overstretch because I did and it was hard to walk the next day. If there is someone who can massage your calves, warm them up with a heating pad and have them use cream or oil to do ROM with your ankles and work up your legs. Be very careful with the joints as they can easily be injured as muscles atrophy. That happened to my left shoulder.
As Vincent stated, medical cannabis can make life with ALS much easier. It is also good for sleep. My cramps are much better since I added THC to CBD but the CBD alone helped a bunch.
