over the past few weeks I have been suffering with itching palms and feet, skin cracking. have been using various creams none working to date. last night I had like an instant bout of flu in which every muscle in my body ached and was sore to the touch, I began shivering with cold. I took Panadol for pain and slept almost 24 hours. eventually I began sweating before feeling a lot better. however today pains have returned to my lower left leg, swelling , hurts to touch and has a flaming red rash, can you advise ?
