Hi I have a dent sort of thing in my upper right thigh. Its been there for years id say. I also have realized I get a lot of weakness in my knee when I work out. And sometimes feel like that leg could give out on me. That thigh is also very tender. I get a very bad pain if someone accidently leans on the thigh or pokes it (i have 2 children) and the pain stays for at least 10 seconds. I remember the dent being there for a long time nw but have never really thought about it til recently as I piece the symptoms together. Is this something I should be getting checked out?
