<s>[INST] I am a 65-year-old female; I was diagnosed almost 2 years ago with rigid-predominant Parkinson s disease. The last couple of months or so, I have been experiencing sporadic pain and weakness in my right elbow, and also (at night only) in my left shoulder. I told my PCP, he has me taking 2 Aleve twice daily. It doesn t seem to be helping. I m wondering if this could be Parkinsons-related, or something else. My next appointment with my PD MD is not for another couple of months. [/INST] hi,thank-you for providing the brief history of you.A thorough clinical examination is advised.Since you been diagnosed with Parkinson this could be a muscle fatigue occuring as the symptoms of the condition. Due to abnormal physiological reactions happening in the brain and lack of signalling to the muscles and leading to over fatigue and over spasm.Now understanding the pathology of the brain and the Neuromuscular dysfunction you may need a muscle relaxant and some physical therapy toake the muscle physiology function well.In my clinical practice most patients with Parkinson have this pains but gets helped better with medicine and physical therapy.Regards Jay Indravadan Patel </s>
