Myasthenia gravis is a disease of bad communication between the nerves and the muscle. It usually presents as fatiguing weakness of proximal muscles (shoulders, thighs, hips), diplopia (double vision), ptosis (droopy eyelids), and can even present with dysphagia (swallowing problems) and dyspnea (breathing weakness). I have not had many patients complain of leg stiffness afterwards (maybe joint stiffness at the knees from not moving around as much). Keep working with your physician. If they cannot help, then ask for a referral to a neurologist who specializes in neuromuscular disease for evaluation of anything from your back down through the nerves in the legs to the muscles in your body.
