If they aren’t unpleasant then the term used is paraesthesia but it is much the same. Dysesthesias and paraesthesias can be quite florid and bizarre.
2. Does the lack of concentration actually result in him falling or does he feel like he will but doesn't actually? If he does fall does the leg collapse and can this collapse be accounted for by weakness in the antigravity muscles of the leg? What is his proprioception in the leg like? – if that is affected could that account for his loss of control He could be having to compensate by relying on his vision and vestibular systems for balance if his leg isn’t giving him proprioception. Is there any reasoning you can do around this to clarify the problem?
3. Failing that an alternative hypothesis is that all the symptoms may be part of a somatoform disorder (Psychiatric disorder) he has developed alongside his musculoskeletal problem. Somatoform disorders come in lots of variations but basically they are characterised experiencing physical symptoms which can’t be explained by medical examination. If so it is not uncommon for patients to be distressed in other ways as well so perhaps you could consider how he seems to have coped with his problem, his surgery and his recovery.
this needs and expert diagnosis. I think it might be time to get an opinion from a pain specialist – possibly a multidisciplinary pain team assessment would be best. They might be able to help work out what is going on. If by chance there is a psychiatric issue they could refer your patient on after ruling out a pain syndrome. That might be better than approaching a psychiatrist first off, as that could well be quite demoralising and alienating for your patient. Are you in a metropolitan city? – that is usually where you can locate chronic pain teams at large hospitals.
All the best with sorting this out.
