Hi, Welcome to Health care magic forum.
It appears that you have
cervical spondylosis, besides the previous diagnoses. The
rash may be a different issue or may be due to the drugs you are using.
I advise you to
consult a rheumatologist for diagnosis and treatment.
I usually prescribe to my patient with such symptoms neurotropic injections, for 10 consecutive days, and then periodically, along with the regular drugs.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods.
Take more of green leafy vegetables, pulses, sprouts and
Protein rich foods to help the recovery.
Wishing for a quick and complete recovery, Thank you.
