text: my wife has lost strength in her legs. she takes 12 prescription drugs. could they be causing the problem? she has trouble walking up stairs, getting up from a chair, and getting started walking after standing up. first of all, you should see your doctor.  taking 12 dugs is dangerous to begin with as it can cause various problems.  maybe think about changing doctors!!!  the drugs could be side effects or could be interacting with each other.  i know of a reputable online discount pharmacy.  it is www.shop4medsonline.com.  this site has information from the us food and drug administration on a consumer safety guide on buying prescription medicine online as well as other tips to consumers who buy health products online.  also on this site is an article from the united states department of health and human services on what a consumer should know before buying any medical products online.  good luck!!!
