My left hand has hard calouse looking knots in the palm area. fingers are beginning to draw up. what could this condition be?

Knots : Knots or nodules in the palm associated with cords or tight bands in the palm that contribute to contracture or tightness in the fingers could be dupuytren's disease. The treatment for this benign, painless condition varies depending upon the amount of tissue involved, the degree of finger contracture, your age, general health and other factors. Id recommend speaking to your primary care physician aobut this and consider getting a referral to see a hand surgeon in your area.

If you think you may have a medical emergency, call your doctor or (in the United States) 911 immediately. Always seek the advice of your doctor before starting or changing treatment.

Fibromas: They are usually palmar fibromas but could be the start of dupuytren's disease.

Dupuytren's: This is a condition that is typically seen in males of northern european decent. It can be hereditary, but does have other etiologies. Contractures can be quite severe & an evaluation by a hand surgeon is often very helpful.
