Hi Tony, ive been on Prostrap 3 for nearly 3 years now, 1 injection to go, and have noticed periods of a tingling sensation recently, especially at night...but this has only kicked off in the last couple of months or so for me and I am going to query it via my CNS at my next appt in October. Hopefully it's just another side effect amongst the many which have come and gone during the HT period!!
Rgds,
Nick
