### input:
i have been getting a dumbness, tingly feeling on my feet. i believe it may be athletes foot. i see my skin is all cracking, when i soak in water i can almost rub it all off. pretty gross. my latest idea is soaking in bleach and water also use powders to keep dry. this is one issue but im not sure if its somehow related to next. this started shortly after feet problem. my left leg hurts when i sit or bend it for any length of time. when i walk or keep straight its ok. hurts mostly at knee. i really feel it when trying to climb stairs too. i had surgery many years ago on left upper leg due to what is called cellulitus. never had any problems or pains since and this was approx 15 years ago. never had any trouble with leg until now. my knee hurts most but pain is thru whole leg mostly when sitting.never had feet problem either. but i just moved to new place and am thinking at least foot problem because of this. i just used bleach to clean whole place as i was told this will help foot problem.xtra info: told by eye doc have high cholesteral due to apparent ring on eye. smoke to much (2 - 20 pack daily approx) which i know i must cut back. bad eating habits (to much grease/oil) i cut down alot though cause of pancreas problems.

### output:

Hither should be an x-ray?MRI of knee and examination of knee by an orthopedic doctorProbably you are developing some mild arthritis, commonest is osteoarthritis, for which Advil or some mild anti-inflammatory medicines are prescribed and some physical therapy. Because of smoking habits, sometimes blood circulation in feet get impaired (Reynolds phenomena) for this Doppler ultrasound issued to diagnose. Talk to a physician/surgeons show to a skin (dermatologist) for peeling of skin if circulatory problem is ruled out
