Tickly sensations

Hi, I was dx in Jan this year and recently been getting a strange sensation mainly in lower back and legs but also arms occasionally. The only way I can describe it is like an excited butterfly type feeling, feels likea tickle all over ththe skin with an urge to stretch this kinda relieves the symptoms for a short while but then they return. Does this sound like a pd symptom or a side effect of meds. I am on rasagiline and pramipexole and 400mg Ibuprofen for joint pain.
