Ask a Neurologist and Get an Answer ASAP
I would suggest you see a neurologist and have nerve conduction testing (i.e. NCV/EMG). This will tell you if you have a nerve or neuromuscular condition accounting for your symptoms. If that test is negative, they can do a muscle biopsy and/or genetic testing.
Hi Sarah. Most forms of MD present present during the first decade or two of life. There are some forms, however, that may not become apparent until much later, especially if the individual has a milder case. The nerve testing might help in this regard. Genetic testing would reveal if there was any genetic relationship to your conditions. Being overweight can bring on mobility issues earlier, no matter the cause, of course, and may also independently cause an increase in CK above the normal range.
CK is an important part of the evaluation of patients with muscle weakness or myalgia, and of assessing patients with myopathies or rhabdomyolysis. But elevated CK sometimes is an incidental finding in patients without muscle-related symptoms or with only minimal nonspecific muscle symptoms (eg, cramps, spasms, fatigue) that do not significantly interfere with activities of daily living, and do not represent pathology. CK levels may also vary depending on one's ethnicity. For example, in one study involving normal individuals, 13% of white Europeans, 23% of South Asians, and 49% of African Americans had serum CK activities above the normal reference intervals.
You need to see a neurologist that specializes in neuromuscular disorders.
My concern would be a neuromuscular condition of some sort, but I could not venture a diagnosis without examining you and having your complete records.
Or ask about nerve conduction testing (NCV/EMG).
