I m 67 yrs old and still quite active. I lift weights and exercise 3 to 4 time weekly. I was told 18 years ago by three different orthopods that my shoulders would need to be replace within two years. Now, 16 years beyond their estimates I m still doing my routines with fairly heavy weights. I ve been controlling the pain until just recently with OTC nsaids. My doctor just recently prescribed meloxicam and it works pretty well. My question is that sometimes it is not enough to allow me to sleep. I ve been adding a fair amount of aspirin and ibu. to the mix. Is that OK?
