After 4 weeks Prednesone was reduced from 40 mg/day to 30 mg/day. Impulse test revealed slight response both in hands and at ankle. However, the perception of numbness in hands/feet remains the same or slightly increased. Now, after 6 weeks stiffness in knee and tightness in upper thighs as also in upper arms (below shoulder) has increased. I consulted an orthopaedician. He says this is due to steroids-induced osteoporosis. He has asked several tests to be done. Let me see what the tests reveal! Will post again
