We rushed my mom to the hospital on her 70th bday for severe back pain. She ended up with shingles while she was there. Aging is an intense rage that goes mostly unfelt so it shows up in physical form such as pain, anxiety, or shingles.
Your leg pain will naturally lessen as another more worrisome event comes into play. The brain can't focus on everything at once, it chooses its battles.
Good luck with the forehead, I always knew we had one for a reason. I suspected it was to hold our sunglasses up.
