I have noticed that my right thumb has more movement in the joint than my left thumb. also i can feel a hard small lump in the base of the thumb joint. it swells after use and aches?

Exams needed: Women tend to have lax joints. A hand surgeon is best to evaluate your thumb. Many heart murmurs are insignificant but a physician or cardiologist can usually detect serious ones. An echocardiogram detects abnormalities of heart valve and muscle,if any. Low blood pressure is often normal in young females but your physician takes a history,examines you and then orders appropriate tests.
