Hello and welcome to HCM,
The presence of pain, swelling, and blue-blackl after a total shoulder replacement surgery
can be due to the surgical procedure.
Trauma to the internal soft tissue
can cause internal bleeding
This hematoma changes its color and appears blue to black to green to yellow.
Since, you are suffering from CLL, get your platelet levels.
Low platelet levels can cause spontaneous bleeding.
However, pain associated with twisting of upper limb suggests muscle pain
will help to relieve the muscular pain
Consult your physician for clinical examination and investigations for know the cause of these symptoms.
Thanks and take care
Dr Shailja P Wahal
