Hi there ~
I understand your concerns. Marijuana may have many effects and feelings of numbness
, both emotional and physical are very common in acute phases of being "high" on the substance, even if it was medical marijuana. You need to follow the doctor's instruction in the amount of marijuana you use to treat your medical condition. I also believe that you should call your doctor's office if you are having these intolerable symptoms although you have been using the medication marijuana as instructed. You will do well with getting the right advise from your doctor.
I hope this helps. Take care and have a lovely day!
