At the very least you should get back the price of your materials. Most say two or three times the cost of materials, depending on what the economy will take. That will give you an amount for your time. You deserve a fair wage for your work. $20 for a full size afghan is much too little IMHO. You could probably sell a hat and scarf for that.
Doctors often prescribe statins for people with high cholesterol to lower their total cholesterol and reduce their risk of a heart attack or stroke. While statins are highly effective, they have been linked to muscle pain, digestive problems and mental fuzziness in some people and may rarely cause liver damage.
Yes, statins as a group can cause elevated liver enzymes. However, this does not mean that they have damaged the liver. Statins can increase ALT concentrations roughly 10% of patients. However, it is rare (less than 1% of patients) that the increase will go higher than three times the normal limit. If the enzymes raise that high, statins should be stopped.
