Darvacet symptoms and conditions

I am 54 and began taking Simvastatin 20mg on Jan 11, 2008 my blood panel showed chol 319 ldl 251hdl 44 trig 118 on Jan 26 I experienced chest pain like I had swallowed an ice cube for fifteen minutes and thought it was a side effect of the Statin I went to the surgicenter and was checked in with Troponin at 0.1 after one hour there I had another pain and they gave nitro g and it continued the Troponin level went to 1.6 They sent me to get an angiogram and I ended up getting two stents. just before the procedure after not having eaten for 22 hours my blood panel was done again and my chol was 155 ldl 89 hdl 38 trig 136. my ldl had gone down 162 mg/dl in fifteen days. after two weeks now taking Plavix as well I began having extreme pain in my joints and both knees forearms and calves, so bad I can hardly walk and have been prescribed Darvocet for the pain. I want to stop taking the Simvastatin I am alarmed at the rate of decent and wonder if my symptoms could be a product of too low of cholesterol. I can't get a straight answer from three doctors I've spoken to. I'm being crippled by the cure

Actually I have a Question, I was experiencing a bad headache Wed.night, used an ice pack, took 3 tylenol & later Darvocet every 4 hours for pain, I woke up Thurs.morning with my neck all red and burning sensation. I am also on Singulair, Xanax, Calcium and womens Vitamins
Please help

I have a condition called Myositis and for the past two years the specialists put me on Prednisone, my condition of myositis is an Autoimmune problem that degenerates the muscles and causes artherites throughout the joints in the body.
I am 58 years of age and survive the chronic pain by taking 5 Mg of prednisone each day along with different types of anti inflaminetery pain killers.
Some days are good and other days require a wheel chair to get around but the side effects of this have caused Cateracts in both eyes, fatty liver tissues and other side effects like mood swings and so on.....

someone gave me a pill that they said is darvacet. i took one, but it didnt do anything for me.the pill is pink and white inside. the imprint says 5114 on one side and a v on the other. what is this pill. i would surely like to know.
thanks juanita
