Cholesterol and triglycerides are not just in the blood, by themselves. like most other substances. Since these are fats, they would tend to separate, like oil and water. To be able to carry cholesterol and triglycerides, they are carried in what can be thought of as protein envelopes, and the combination of fats and proteins are called lipoproteins.
Dysliprotinemea indicates that the lipoprotein levels are abnormal. The type refers to the pattern of abnormality of the lipoproteins. However, the management is guided by the actual numeric levels of the various lipoproteins (LDL and HDL) in the context of the clinical situation, not the type. So, you and your doctor will really focus on the actual numbers.
If you can provide the specific numbers, then I can comment further.
No, there would not be any correlation between these lipid values and your pain.
As for the actual numbers, none of these values are so bad that it is recommended to treat with medicines. Of these values, the primary numbers that can stand to be improved are the triglycerides and the HDL cholesterol (which is the good cholesterol, so it is better for it to be higher). The recommended intervention for values at this level are to be eating a healthy low-fat diet and getting a greater amount of regular aerobic exercise.
