hi, First of all its sad to hear you had 4 THR on one single side. Well, now the pain you are facing from hip till the toes is nerve induces. What will be happening is due to the weakness in the core muscles, spinal muscles and hip muscles this sort of pain arises. It is not difficult to get rid of the pain. Infact it will be more easy and by doing certain exercises your hip will also become stronger to hold the THR implant. Try to meet up a physical therapist who can assess you once and then guide you exercises for core stability, spinal muscle strengthening and hip muscles. As when exercises are performed under supervision there is always a benefit for accuracy and no chance of having any other issue. You should work out on both sides rather one side. As body functions as a single joint unit. Unity is the biggest strength, so when all the muscles above and below the hip joint becomes stronger there will be no chance for the hip to dislocate again. Also, this will be a little slow process, but it will surely help you. I have seen many cases with THR and some really unimagined cases, but to be honest with the grace of god all went well with all of them What you need to keep is the patience and faith in your own self to strengthen the muscles, which will give you immense stability for you. If you have more question you can ask me directly, Thank you
