I just turned 80 and suddenly my running times have worsened from an 11 minute mile to a 14 minute mile -my hips and legs are so tight that it s difficult to touch my toes as a warm-up and run more than one mile -- and most scary is that my shoulders and biceps have suddenly become so aching and tight that my usual 30 push-ups daily are so painful that I can barely do 20... Is this just because of my age or could I have suddenly developed senior arthritis or some kind of disease?... Thanks for whatever you can advise.
Hello, I have studied your case with diligence. If not relieved then possibility of polyarthritis needs to be considered Chat Doctor.  There is reduced chest function in this disease. Stiffness in spine is increased do you have such stiffness in spine? When such patients come to our hospital I advise them blood test like RA factor, CCP, ESR, complete blood count, HLA B27Hope this answers your query.
