Quadriceps symptoms and conditions

I am a 60 year old male. I have been on high dose Niacin for more than 12 years. 2 years ago I started taking the combination drug, Advicor. (Lipitor and Niacin) Up until this point, there were no side affects with the Niacin other than occasional flushing. Since starting on the Advicor I have noticed a gradual weakening of muscles, and occasional joint pain. I have recently increased my exercise, thinking this was part of the aging process. I have not worked out consistently for 2 years. I have not noticed much improvement in my conditioning in the past 3 weeks, and have in fact noticed my quadriceps feel as though there is a buildup of lactic acid. I also notice my heart rate does not climb very high before my perceived exertion is above 50%. I did a fitness evaluation today at the health club I go to. The trainer mentioned that he hears the same thing from a lot of people who are on Lipitor. He went on to say, there heart rate is usually 20 bpm lower when on the drug. I am going to be talking with my physician to see about getting off Advicor and going back to just the Niacin. I will increase my exercise and more closely watch my diet. I want to thank the folks who have posted.

I was placed on Doxycylcine for Epididymitis, which is an inflammation or infection of the epididymis, a convoluted duct that lies on the posterior surface of the testicle. I took Doxycycline for one week. 100 mg twice daily. I ate a meal with every pill. I did not experience nausea or vomiting like I see many did. I did however have fatigue, loss of appetite, diarreha, increased anxiety (I have anxiety and panic attacks), depression, agitation, pains shooting down the back of my quadriceps, abdominal pain and some acid reflux type symptoms towards the 4 th day of taking this drug. It has been a little over a week since I finsihed this drug and I am still having pains down my right leg in in different places, when I sit or lay down is when it is most painful. The doctor can only describe it as a possible slipped disc. How? I was bed ridden for a week! The pain in my leg is not severe but very annoying! Like others here my doctor says that he does not see how Doxcycline could cause this. I will never take this drug again! I will from now on request Zithromax. I have had to use Zithromax quite a few times in my life and have had no problems with it.
