Dear Anna,
Welcome to this forum! I can only speak for myself, but I have not experienced weakness after an attack as you have described. I have had secondary Raynauds for over 30 years. The problem I have after recovering from an attack is that of stiffness and a lack of dexterity. I’m hoping others will jump in and share their experiences with you.
However, I would recommend that you see a Rheumatologist to be fully evaluated.
Best of luck and thank you for your post,
