Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
Your blood tests are quite normal except for a high LDL. You need to do regular exercise, at least half an hour per day, avoid oily, fatty and junk food. Then your LDL
cholesterol may come down to normal. If in spite of all these things it doesn't come to normal you may have to be started on lipid lowering drugs like
Atorvastatin.
But this is not related to the generalized itching which you are having.
You might be having some allergic rashes.
Allergy can develop due to several reasons- some foods like egg, fish, pollen grains, animal hair, nylon, terylene clothes. Just try to find out what you are allergic to and avoid it. Try
home remedies. Apply coconut oil daily three times a day for one week. If you are not better
consult a dermatologist.
Hope I have answered your query. Let me know if I can assist you further.
