I had hip replacement surgery 3 weeks ago. I take the following meds: Simvastin (since 2010), celebrex (since surgery), asperin (post surgery blood-thinner), tylenol ,(post surgery pain), multivitamin and occassionally alleve ( 1 every other day or so). I also use, but am weaning myself off of a walker. I noticed my hands are significantly weaker. At first I thought it was from leaning too heavily on the walker, but as I am leaning less and still feeling the weakness, I wonder if it could be a side effect of my meds???
