This looks like an eczema that occurs on the hands and feet. You need to wash your hands in a mild soap, rinse well, dry well, and then work in lots of emollient cream, especially before sleeping at night. Do this every day. Stress can sometimes start it off.Do you work with metals of any sort? You can also try taking an antihistamine one a day to lower the inflammation. I’m guessing this is why your ESR is raised.
A cholesterol level of 290 is something to take seriously. Do you have a high fat diet? Are you overweight? Do you smoke?The muscle cramps may be associated with the high cholesterol.If you smoke try to give up and also look at your diet…try to cut down on all high fat/salt foods.However, you really need to consult with a doctor about this who can advise you on the best way forward . If you are 50+ then you should see a doctor soon.
Thanks a lot Marina_Dee for the advice. It helps!
