Just hope you are feeling and keeping much better by now.
My friends hubby had to call in the doctor because he went off his legs and was in great pain. His doctor asked him if he had sprained his ankle......... Later in the evening my friend had to take hubby to the A&E where they just admitted him and he went on am antibiotic drip for 3 days................... he had cellulitis and they thought it had gone into his bones. He is at the moment 'fighting' his GP to get a referral to go private and see a bone specialist for his legs. So far no success.
