If this a problem that worries you and your doctor rebuffs your concerns with " Yes, it’s a age thing." GET ANOTHER DOCTOR.
I hate it when doctors completely blow you off. My mother, having problems walking, accepted it as AN AGE THING and that eventually she would have to have hip replacement surgery.GAWD save me from the martyrs in my my life. She was to the point of not being able to go anywhere and getting around the house was very painful. I told her to go to the doctor or I would put her into a home and sell all her beloved trash for a quarter (she’s a pack rat). The Doctor prescribed therapy and this is a woman who has not had a phsycial non-housework related work out since 1944. She hated it and it wasn’t helping. She resigned herself to the pain. Finally someone recommended she go to a chiropractor. Afterall, what could she lose, she was barely walking at all. He discovered what her own doctors missed, that one of her hips is lower than the other and it was because of a horseback riding accident she had when she was 14. (He didn’t tell her this, he’s not physic,she told him) He didn’t promise anything, but they did adjustments on her and she is 75% better. She will never be 100% because she does not know how to take it easy.
Ready for armchair quarterback diagnosis?
It sounds as if the circulation is sluggish. You may want to try stetching and yoga exercizes. Easy to do and no special shoes from Rebok or Nike required. And you can do it while watching TV. Or maybe your underwear is too tight
