I had 5th metacarpal surgery about 3 months ago and have ever since had severe pain in my hand, wrist and stiffness in fingers. i lifted a few heavy items last week monday whilst moving houses and have been in excruciating pain?

Crps: CHRONIC REGIONAL PAIN SYNDROME or RSD is an autonomic response to rare prior injury. If you have developed this, a stellate ganglion block should help. Hope all this helps

See your surgeon: After 3 months, a metacarpal fracture should reasonably be expected to be healed. Some degree of stiffness and weakness is not atypical but your description of pain is atypical. You should see your surgeon and have an x-ray to assess healing. It may be that your fractures has not healed, you have hardware issues, abnormal scarring or even infection. Its worthwhile to investigate this further.
