you can get it pretty much anywhere. Walmart, Target, Walgreens, Amazon etc.

it takes a while to really tell its working.

physical labor is so hard on your body. My husband has worked it for almost 20 years. I'm sorry that ibuprofen has quit working for you. Voltaren is another type of NSAID, but it's topical not oral. I think it helps more because it is put on directly where you hurt. You could also try pain patches. There are several types. Salon Pas seems to work well, if you can handle the smell of camphor. There are also several options for lidocaine. (Patches, creams, gels, etc) I wish you luck on finding something that works for you. 🫂 🙏
