<s>[INST] My husband had scaphocapitate arthrodesis with bone graft 3 weeks ago. All as well. His wrist is now in a cast. Today he started experiencing a bubbling sensation that started in the forearm and traveled to the operated wrist. It lasted a few minutes. It has gone away. What could this be? [/INST] Dear Sir/MadamI have gone through your query and read your symptoms.In my opinion, such sensations are usual when the patients limb is in the cast.take care that no organism like ant enters the cast, do not wet it inside, watch for itching in the cast, if you face any of these then see your doctor.I hope that answers your query. If you want any more clarification, contact me back. </s>
