Hello and welcome to HCMTyphoid
is associated with faint red colored patches called 'rose spots'. They are 2-4 mm in diameter. They occur in groups of 5-10 and are seen on days 7-12 after getting the infection.
They occur as a result of bacteria being carried to the skin. These spots are common on lower chest and upper abdomen.
It is difficult to tell whether it is a side effect of drug or not without knowing the drug used.
The other possibilities are skin lesions like systemic lupus erythmatosis, discoid lupus
Consult your doctor for correct diagnosis and treatment.Tingling sensation
is not an usual feature of cancer.
Thanks and take care
