I am interested to know what solution there is for someone who suffers from an insulin allergy everytime they inject themselves. There symptoms appear within 15 minutes of taking protophane insulin as well as novorapid. There Blood sugars are unstable.They include diminished sensation within all fingers on both hands consistently . Last allergic reaction for this person was hospitalisation with symptoms of sore throat including swelling and ringing in ears. Are they connected?This person is no longer on Lantus.They currently take Novorapid three times aday but feels the diminished sensation within hands immediately within taking dosage as recommended by Doctors. A nerve conduction test was done recently and there was a strong possibility that it was carpal tunnel syndrome. The client disagrees with this diagnosis and firmly believes the insulin is causing an ongoing negative affect. They are currently on novorapid TDS 34unis/36units/34 units and protophane. There is insulin changes which tend to be ongoing as we speak. Any input would be much appreciated.
