Hi Chop Styx, and welcome to HW.
I'd echo what Stray says about needing to see your GP. Two months sounds like too long for a straightforward muscular problem, and it's much better to be safe than sorry where spinal problems are concerned.
CRPS since 1999, diagnosed in 2005 and since spread to full body, spasms, dystonia & contractures, gastroparesis, orthostatic hypotension,bradycardia/tachycardia, bone spurs, bursitis, carpal tunnel syndrome.
On Oxycontin/Endone, Topamax, Mobic, Magnesium, Florinef, Midodrine, Somac, Cipramil. Have a spinal cord stimulator, intrathecal pump with baclofen & bupivacaine and doing physio.
