<s>[INST] I have pain on the back portion of my left thigh since 24 hours. It s a little swollen but it doesn t pain when touched or pressed. It hurts a little when i stretch my legs. I have applied Ice gel twice but the pain isn t reducing. Moreover i feel that its paining internally as it doesn t hurt when i touch or press it. [/INST] Hello, It thinks if you have tried putting ice over the painful area that is the thigh muscle which isn't helping you then try putting it over the lower back region. If this helps you then this could be a nerve root entrapment and will be treated accordingly by a physiotherapist. Try icing the lower back and see if there is a change in symptoms. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist </s>
