Suffering Elbow Pain From 1 month.

My mother has been suffering elbow pain for 1 month. Visited near a local ortho doctor following the prescribed medication (Etoshift-MR 8mg, Win-TBR, and multivitamins) and utilizing the recommended tennis elbow support belt, she has not experienced relief. In the past few years back, my mother found relief from knee pain through the use of Jointace DN (Glucosamine, Diacerein, and Methyl Sulfonyl Methane). Considering this positive history with Glucosamine, we are curious if it could be a potential option for her current elbow pain. I have attached the prescription and X-ray for your review. We value your expertise and would appreciate your guidance on whether Glucosamine might be suitable or if there are alternative medications or therapies you recommend.
