<human>: my brother has had cancer 2 times resulting in him having part of his spine and a kidney removed. he is now 49 and has been using heroin for almost 3 years, he has had 2 episodes in the last 6 months that consist of him not being able to walk and move his legs and the pain is unbearable. the first time he went into the hospital and they said he had MRSA, this time they said they found nothing. Any idea what this could be?
<bot>: Hello, The causes for leg pain and inability to walk are:1. Injury2. Blunt trauma3. Sprain or strain4. Electrolyte Imbalance5. Sciatica6. Improper posture can take tablet Diclofenac and apply diclofenac gel or cream. Also, apply ice locally and do x-ray and MRI of hip region. Treatment mainly depends upon underlying conditions. Kindly follow with detailed history or consult with orthopedic. Hope I have answered your query. Let me know if I can assist you further.
