I know it can't be muscle yet it's just to soon!

Any wisdom would be greatly appreciated

Could be you've over-inflated your thighs. Try unscrewing the valves and letting a bit of air out. Don't inflate beyond maximum pounds/per/inch or they might blow while riding or jogging. A floor pump with a good gauge is helpful.
As to your jeans fitting problem, don't pump them up to full pressure until after you've put on your pants.
