Dear Matt Cresta,
What are the specialists you have seen?
What kind of therapies or medical treatment have been advised?
What is your Back MRI and ultrasound of legs saying? Any blood work done?
Do you have any back pain?
Since when do you have these problems?
Are you on any medications?
Do you have diabetes or hypertension?
I assume that your back MRI is normal and colored Doppler study of leg showed no deep vein thrombosis. With your symptoms the best specialist to consult would be MD in physical medicine and rehabilitation. These PMR specialist are called physiatrist and are specialist in musculoskeletal and neurological rehabilitation. Clinical immunologist or rheumatologist are the other specialists, who may help you.
The first intention is to diagnose the condition. Getting an EMG (electromyography) of the leg muscles, should be the initial step. Getting the following blood steps would also be advised;
Anti-SSA (Ro) or Anti-SSB (La)
The mainstay of the treatment should be physical therapy of the lower limbs. Initial stretching exercises are the essential component. Deep therapy like Iontophoresis, phonophoresis, electrical stimulation may also help. Anti-inflammatory analgesics or analgesics like tramodol may also be advised by your physician.
Please feel free for your follow up questions.
You are welcome.
