Hello Doctor, I m an active 59 year old male who lives in the Pacific Northwest. I ve slowly been developing an increase of muscle fatigue, particularly in my arms, along with some tingling in my hands and feet, and slight swelling in my hands causing my hands to feel some minor, unusual pain. I ve also had an increase in discomfort in my shoulder and elbow joints extending down the nerve into the middle of my forearm. It feels like the pain you get when throwing a baseball for the first time in a long time, or over throwing it! Any suggestions as to the things I might start considering? Sorry I can t be much more specific without being overly wordy. Thank you for any advice.
