Fore arm pain

[als30]

Looking for advice
Partner had a accident several year's ago had glass in his forearm accident with a glass door was told he was lucky to be here as it just missed main arterie (this happend all before i met him)
Had 2 operations to fix it but 8 month later and now the pain is really bad arm and hand swell up plus goes cold and purple now on tramadol to help with pain
Any advice on what it may be
Also been back and forth to hospital and docs nothing

Not a doctor but maybe reflex sympathetic dystrophy? See a doctor.

Has been back and forward was admitted to hospital just before new year as pain was severe but let out next day etc waiting on surgeon again for another opinion

Here is a link about reflex sympathetic dystrophy

Thanks for that ill pass that on sounds similar

Hope you get some answers.

Hope so too least we can ask if its that
