1st post open to advice

Hi I'm new to the group having been diagnosed nearly 5 years ago with RRMS which just like us all here turned my life upside down. Before finally diagnosed I was treated with demylination trialled several different medications before they finally confirmed (what my GP all my life had prepared me it basically was). Try a tell a long story short as I can. I have just started Tecfidera for the 2nd time as first time round I decided to stop taking them completely as I felt myself diteriating with more tiredness, severe mood swings, lack of appetite and body was constantly in pain. Well I have managed without with only q hand full of mini relapses, but specialist and MS nurse have told me I have to start back at step 1 again... 10 days in and my feet are in constant agony (doesn't help I manage a busy bar) but I'm after any advise someone my have to ease the pain when I'm not working and able to relax... Has anyone tried the ice pack/heat pack slippers? TIA
