I have experienced them off and on for several months, maybe years. No swelling redness. There maybe "tenderness" in calves. It feels good to massage them.
Take Singulair, Advair, Omeprazole, Lantanoprost and Timolol and supplements, emphasing Calcium and Vitamin D.
Had right middle lope of lung removed 3 months ago because of a carcinoid tumor. No further tumors found. I had the leg aches before that surgery.
I would be happy to assist you further, if you need any more information.
