Relapse/ Long COVID?

Hi 👋 everyone, I wonder if anyone can offer me some advice. I tested positive for COVID in Jan 2022. Symptoms mild, mainly cough, brain fog and fatigue. Appeared to recover ok with help of anti-viral medication (molnupiravir). Feb 2022 had chest infection which needed antibiotics. Lots of family and work stress added into the mix. Roll on April- I have been off work for 2 weeks with fatigue/ recurrence of old MS symptoms/ painful legs and during the night I get really bad restless legs/ lhermitte’s to the point where I wake up. I wonder if this is a sign of a new relapse or post viral or both? Would love to know if anyone has had any similar experiences. Much love ❤️ xxx
