Hi there, This is Dr Basu, Experienced Specialist. I am here to address your concerns and provide great service.
It is likely you have adavanced stage osteoarthritis in your left hip joint.
That can cause shortening of the leg as well.
There can be nerve involvement supplying your leg causingall these symptoms.
The arm and head pain can be related to the arthritis in your cervical spine.
So you will need MRIs of the cervical spine and the hip joint for further assessment.
Also your lumbar spine may be affected as well.
So MRI of lumbar spine is also required.
Steroid injections in the joint and also in the spine provide long lasting relief.
YOu will also need physical therapy.
Oral medications may be helpful short term like gabapentin, Naproxen and Flexeril ( muscle relaxant) combination.
Nortriptylin also can be added at bedtime.
In case of severe pain you should go to the local hospital for IV pain medications.
Then you should consider consulting with an orthopedic consultant for further evaluation.
