Swallowing and pain in Esophagus

Hi I have suffered badly for last 3 wks with this - does anyone else suffer? I had been advised to take dompierone anti sickness tablets and diazapam - it’s seems to have settled last few days but the fatigue is awful now and my legs are sore, heavy and tired - do u think I have had another relaspe or is it common don’t know when to phone ms nurse ? I only ever think a relaspe means if I can’t walk totally immobile as I was only dx June - any advice welcome. Kellie
