U can try Hyaluronic acid gel injection & PRP for the later stage. There is no pain for the injection as local anaesthetic kep will be given prior to the gel jep. However, effectiveness of the jep will be vary by patient conditions & Dr’s skill in getting the right position to jep.
I hv just have my hyaluronic acid gel injection done yesterday to both of my knee near 1 of the clinic in ss 15 subang which immediately lifted my knee osteoarthritis pain that’s follow me for couple of months. Hopes you find your pain remediation soon.
